Have you tried using the 5.11.14 kernel? I assume you have an integrated AMD GPU; I have a very similar notebook (E495, same CPU) and something very similar happened to me after April 9th’s update (only that I’m using KDE instead of GNOME).
I wrote a post at this forum and I think I solved it by doing a kernel upgrade there. My guess is that a very recent commit at 5.11 kernel solved some page fault overflows (which was a very common error in my case, and may be in yours). You can read the whole post if you want to, or contribute with your experience! Maybe someone else can help you there. But TL;DR try using the 5.11.14 kernel, hopefully it helps you.
