Default Animation Editor Startup Glitch (Softlocks Studio)

Hello! First time posting.

I keep getting an invisible error after using Roblox Studio’s default Animation Editor. It happens when I first select a model and proceed to animating.

I think it may have something to do with custom models, since it only happens on custom ones. If I play around with the Motor6D’s on the model it goes away, but it is still quite annoying and requires task-manager intervention.

I’m not sure but I think that there’s a post about it somewhere in the #platform-feedback:studio-bugs section.
Don’t know how to fix it but I know that you can simply change your animation editor to Moon Suite or Legacy (basically the older version of Roblox’s default AE).
