10 Breach Map froze in unending "Escape pressed" animation loop during breach

Ryzen 9 5900x
RTX 3080 Ti
4k, Details set to Low-Mid with DLSS Performance
HDR on, Reflex on, Culling on, Target framerate 60

Map: Blooming Field
Waystone: T16
Modifier: Boss, Breach, Irradiated

On the 3rd Breach, I saw a Boss spawn roughly 10 seconds into the breach

Some sound started to loop in the background (tormented "agguahguu" idk) for a maximum of 1 or 2 seconds

All animations continued to play, but the screen was frozen as if you pressed Escape

All menus could be opened, but no CTA or item could be pressed

Return to Character Screen was not possible

Had to force close the client

When I returned to the game, I was back in my hideout, map portals were closed

Map now counts as attempted, although no death was registered (no EXP loss)

Edit: I got my Waystone back (it's in my Stash again). Thank you for that :)

Other than giving you the above I really don't know how to reproduce it, and I sure as hell hope I don't ever encounter this again.

It hurts like mad to lose a wonderful map like this in such a fashion. My disappointment is immeasurable and my day ruined.

Not really but it does sting
