Plasma not staring under wayland (but it does in X11)

Help

From a prior update I lost the ability to start plasma in wayland mode.
The login manager works, and I can log in to a X11 session, but if I choose wayland the screen goes black, and then it returns to the login manager.

I hoped that it would fix itself with the update to 6.4, but it hasn’t been the case.

I’m running a KDE slimbook, with KDE Neon, and the only information I’ve been able to get related to this issue is the following segfault:

[  198.678569] kwin_wayland[4267]: segfault at 0 ip 00007bbcf4cda465 sp 00007ffc04c82fa0 error 4 in libQt6Gui.so.6.9.0[2d9465,7bbcf4c51000+62f000] likely on CPU 0 (core 0, socket 0)

any help would be much appreciated
Best regards

Can you post (or create a bug report) with the backtrace ( Guidelines and HOWTOs/Debugging/How to create useful crash reports - KDE Community Wiki)

What GPU do you have?

Does Wayland start using a new user?

I can’t create the backtrace, if I use coredumpctl --reverse it says that there is no coredump.
And as it happens in the login screen, I don’t know how to get the information. The one I got was from dmesg.

It happens with a new user too.

The GPU is an intel integrated one:
VGA compatible controller: Intel Corporation HD Graphics 620
