I'm also having problems like this with large files.  I haven't been able to 
narrow it down but I'll try what you say about org-startup-folded.

Do you also have a problem where sometimes TAB or SHIFT-TAB on a heading has no 
effect?  Some Org files seem to get broken after editing them for a while, and 
some folding no longer works (that is, some headings stay closed, while others 
can be cycled), and the only way to fix it is to reload.

I'll turn on debugging and see what that says.

Before you try anything weird, can you do the following:
(1) Update Org to the latest version and make sure that M-x org-version
    reports Org 9.5.3
(2) Remove org-persist-directory
(3) Try to see if the error persists

Thanks for reporting!
Can you please share the exact output of M-x org-version?
If you really see 9.5.1, then you likely have a "mixed" Org installation
with some code in your init file first loading built-in Org mode and
then loading the newer version. Such state can cause all kinds of bugs.

The latest Org version is Org mode version 9.5.3 (release_9.5.3-1799-ge73d5b)
The latest stable Org version (distributed via ELPA) is also 9.5.3

Best,
Ihor

sorry. I sent a false message yesterday。I try again today. even upgrade to Org
mode version 9.5.3 (9.5.3-g277897), The problem still exists. But I find
out something new。you can see my *conclusion*. And I send all my emacs org
state.

   - My Observation
     - if setting org-startup-folded t , enable org-indent-mode, open the
large org file, emacs get stuck, the mouse can't move。
     - if keeping org-startup-folded defaul value（i.e  "showeverything") ,
enable org-indent-mode , open the large org file, get a warning, but not
get stuck:
       #+begin_quote
       Warning (org-element-cache): org-element--cache: Unregistered buffer

       If this warning appears regularly, please report it to Org mode

org-indent-mode , open the large org file, everything works fine.
     - if setting org-startup-folded t, disable org-indent-mode, everything
works fine.
 - conclusion
   - enalbe org-indent-mode cause the warning : "Warning
(org-element-cache): org-element--cache: Unregistered buffer modifications
detected."
   - setting org-startup-folded t, enable org-indent-mode. Having both
causes emacs get stuck.
   - In addition，it's not accurate to say that emacs get stuck. To be
precise, emacs get stuck, the mouse can't move for a few seconds and then
it works find.

Is the no more warning text? The warning you are seeing should continue

sorry. I'm not good at email communication. This is my first attempt to
submit a bug report to Emacs. Maybe I could add CC to  emacs-orgmode@gnu.org on
the recent email that shows all my emacs current state info.

Thanks!
It appears that something is editing the buffer either before or after
loading Org mode.

Can you share the values of change-major-mode-hook and org-mode-hook?

Also, do you deliberately drop the CC to emacs-orgmode@gnu.org and
prefer the conversation to be not public?

Best,

I search change-major-mode-hook and org-mode-hook by C-h v(describe-variable).
the result is

```
change-major-mode-hook is a variable defined in ‘C source code’.

Its value is (font-lock-change-mode t)
Local in buffer *Help*; global value is
(global-company-mode-cmhh yas-global-mode-cmhh smartparens-global-mode-cmhh
ctrlf-mode-cmhh ace-pinyin-global-mode-cmhh meow-global-mode-cmhh
global-eldoc-mode-cmhh global-font-lock-mode-cmhh)

Normal hook run before changing the major mode of a buffer.
The function ‘kill-all-local-variables’ runs this before doing anything
else.

  This variable may be risky if used as a file-local variable.
  Probably introduced at or before Emacs version 19.23.
```

```
org-mode-hook is a variable defined in ‘org.el’.

Its value is shown below.

Mode hook for Org mode, run after the mode was turned on.

  This variable may be risky if used as a file-local variable.
  You can customize this variable.

Value:
(#f(compiled-function
    ()
    #<bytecode 0xbfc639b2ee0448f>)
   #f(compiled-function

Sorry, I missed that. Unfortunately I do not see anything suspicious
there.

Now, it is confusing. I am unable to reproduce the warning on my side
even with org-fragtog and valign installed.

Can you try to reproduce the problem starting from clean Emacs state
(emacs -Q)? See https://orgmode.org/manual/Feedback.html

Just use "Reply All" in future.

thank you for reminding me to use this method.


I found out why. package *valign-mode*(https://github.com/casouri/valign)
causes the problem:

(add-hook 'org-mode-hook #'valign-mode)

If I don't add-hook for valign-mode, everything works fine.

valign-mode causes the problem. Try these steps to reproduce the problem :
add-hook for valign and open a large org file, then try moving the mouse a
few times，quickly TAB and SHIFT-TAB a few times.

Thanks! I have opened an issue in valign repo:
https://github.com/casouri/valign/issues/30

This problem needs to be fixed on valign side.

After further investigation and discussions with Emacs devs, the issue
has been fixed on Org side.

Fixed.
