Minecraft 1.16.1 forge crashes when starting?

I want to play with forge on 1.16.1 but it always crashes while loading and I always end up in launscher.

The server starts without problems with the same mod. This is my log:

That's because it's still the Forge Beta. Try it out with Forge 1.16 and minecraft 1.16.1 together that should work.

But forge does the version automatically. You mean forge 1.16 with 1.16.1 mods?

Yes

Ok I'll try it later thanks

Can it be that there's only forge for 1.16.1 or am I stupid?
