Yes, please submit bug reports for those issues with as much relevant
support data as you can, including any relevant customizations.  E.g.,
for desktop.el-related issues, please post the .emacs.desktop file
that causes those issues.

Thanks.

FTR, Emacs 28 never crashed on me due to anything related to
desktop.el, which I use all the time.  I also never saw any problems
with removing .emacs.desktop.lock with v28.1.
