5.0 EA: I have constant crashes average every 5 mins. I tried almost every solution

As in the subject. I am loosing my mind and patience. Even quite simple scenes can crash, it’s not easy to reproduce on light scene, but on heavier scenes it is every time (opening material editor and selecting a texture node, for example). I think it could be something with UI or something.
It crashes like mad with a crash summary attached below.
I have a decent PC, RTX 2080, i9-7940X CPU @ 3.10GHz, 128gb ram, Full HD display.
4.26 does not crash at all and I use it every day.

Here’s the basic crash report, perhaps someon can relate.
