When I take a screenshot everything goes black... The thumbnail worked, but I have to re-join to see everything again. https://youtu.be/9E06uk0qK5k

I'll look into it soon!

I see you're using a bunch of mods, could you please verify that the same issue happens without any other mods. Or if it doesn't, list the minimal combination of mods with which it happens and their exact version.
I tried it with my 1.18.1 instance and it seems to work fine there.
