Game bugs when unequipping the Morior Invictus Grand Regaliar.

When I try to unequip my Morior Invictus Grand Regaliar, the game disconnects me and returns to the login screen.

I've tried checking the files, updating the video driver, using both Vulkan and DirectX 12, and the error still persists.

I can't unequip the item at all. When I try, in addition to crashing and being disconnected, I suffer a small rollback in the game.

I'm using the character RCA_RAKE. (Bloodmage)

Can you please help me? Can I share the screen, record video, etc.

---- EDIT -----
For some reason, it started working again!
From yesterday to today the bug disappeared!
