I've attempted to disable the element cache using `(setq org-element-use-cache nil)`.

However, it seems that cache is still in use, because I'm regularly getting org-element--cache errors like:

⛔ Warning (org-element): org-element--cache: Org parser error in todo-routine.org::55572. Resetting.
  The error was: (error "Not an Org time string: <2024-0-15 Sat .+1m")

This particular warning may also happen when cache is disabled.
You encountered some error with Org parser.

Any chance you can create a reproducer?

Yes. Looks like this particular error is related to org-startup-indented:

1. Create file reproducer.org with contents:
* TODO item
DEADLINE: <2024-07-10 .+1d>

2. Launch Emacs with org-startup-indented=t:
$ emacs -Q --eval "(progn (require 'org) (setq org-startup-indented t))"  reproducer.org

3. Delete one character from the date to make it invalid. For example delete the "4" so that the file becomes:
* TODO item
DEADLINE: <202-07-10 .+1d>

4. Observe the error:
⛔ Warning (org-element): org-element--cache: Org parser error in reproducer.org::13. Resetting.
  The error was: (error "Not an Org time string: <202-07-10 .+1d")
  Backtrace:
nil
  Please report this to Org mode mailing list (M-x org-submit-bug-report).

Thanks!
This appears to be an old bug in the parser.
Fixed, on main.
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=9f4f7338d

Not for bugfix release as I do not want to break the parser accidentally
without testing, and the problem appears to rare enough to not call it
critical.

Tested the fix, the problem seems to be gone. Thank you!

However, regarding the original problem about cache seemingly being active - I do often notice that there are other issues with text highlighting (dates/todo markers/etc) and indentation breaking seemingly without reason. I will keep looking for these issues, but making a reliable reproducer for them is hard.

To be 100% clear, cache might get activated for short periods even when
you set org-element-use-cache to nil. But that happens only for the
duration of a single (expensive) command and the cache is discarded
immediately after. It may theoretically cause problems when you perform
some kinds of commands that edit multiple headings/other objects in
region: org-encrypt-entries, org-decrypt-entries, setting tags in
region, setting deadlines/scheduled in region, and archiving.

Text highlighting in particular should not be affected, AFAIK.

If there are problems with fontification, you may try setting
`backtrace-on-redisplay-error'. If there are any problems during
fontification, the last one will be recorded in *Redisplay-trace* buffer
(the buffer itself is not auto-displayed, you need to switch to it
manually).
