Hello there,
I can see that this issue is resolved, but i fail to see what the solution was. Could you please share the steps you took to resolve it? Or was it a fresh install as you said on your latest comments?
I do have a similar issue as posted here Desktop randomly restarts
After looking more into it, i have concluded that Wayland is still unstable with NVIDIA drivers which seems to have a lot of issues occuring due to that combination. I do have NVIDIA on my Lenovo Ideapad 3 Gaming and the issue you are stating here in your comment is exactly the behavior i get.
Thank you very much in advance
