Renders have become impossibe 9 out of 10 times
I run a Ryzen 7 3700X with a RTX 3060, no tweaks. I will gety black renders or black renders in scenes which previously worked. I could set up to three figures in a big scene by PW productions and the machine too kit. Not anymore.
I often get something like this in the log:

I might have found the rat in the end. Subdivision for render on my figures was at 5 instead of 2 x_x
