Failed to uncompress animation

Hello Everyone,
I played this league quite a lot but since the patch for 3.2.6 the game frequently crashes to Desktop with diffrent error Massages all related to Rigs which failed to uncompress diffrent animations. Sometime its Hargan sometimes Lily etc.. I use the luxury Hideout an already tried clearing it of non essential NPCs but that didn´t help. The crash mostly occurs when i load in or out of the Hideout. I already tried to check the gamefiles via steam but it didn´t find anything wrong with it. And i already tried reinstalling the game. I also switched between Vulkan and DirectX12 nothing made a difference. All Drivers are up to date
Im Playing on an

Intel core i7-13700K
Nvidia Geforce RTX 4060

Would appriciate any Ideas.
