@mithune0000 Yes, that's what I wanted to see. Please create a report at bugreports.qt.io and append this trace.
Thanks!

Few things I observed in the stack trace -

Don't set any LD_LIBRARY_PATH globally - you must not mix up different Qt versions or installations and it only makes trouble (as you can see).
-
@Christian-Ehrlicher I tried few options -
-
Remove LD_LIBRARY_PATH, source
zshrcand run qt creator. -
Remove all the envs related to Qt, source
zshrcand run
Still getting the same error

zshrcis not taking the effect ? -

Even after fixing the LD_LIBRARY_PATH, its crashing

Then please install the debug symbols for QtCreator (through the maintainance tool) so the backtrace is more useful. Thx.
-
Maybe switch to Xorg and try it out as well to see if there is any crash. If not, file a bug report specifically for Wayland.
@JoeCFD said in Qt Creator 16.0.0 is crashing when opening cpp files:
file a bug report specifically for Wayland.
When you look at the backtrace you see it's crashing inside QtGui, no wayland plugin anywhere... but we need debug symbols to see what happens.

I uninstalled all the version and reinstalled the latest version using installer, it seems to be working better. I am gonna keep an eye on it, if it happens again, I will open this thread again.
