Reshade doesn't work, arenas don't work!

Someone has this problem, is it due to the last update of the game?
I can't load my reshades, nor can I load arenas made by other modders.
can someone help me, does anyone else have this problem?

I can load arenas by other modders after the latest update.

I have this problem too with arenas. I'm not sure on how to fix it. For reshades, try updating the reshade application.
