POE2, crash on Login, specific character only, "Unrecognised task"

Bug Report ID: #2079089227

Not sure if the Bug Report ID helps, as it was created on another character, but my game crashes on login every time for my Witch.

After a crash with this error message in game, I am now completely unable to access the witch at all, the crash message repeats at every login.

I have tried:
Restarting/Reboot
Repair game through Steam
Change Shaders
Delete Game Caches
Delete Config
Remove Filters


Error message is "Unrecognised task serialised by server; missing registration?"

I have the exact same issue on my Witch in The Drowned City. Also tried all the listed solutions, to no avail. Grafitch

Wait until the instance you were in get's removed (10 minutes i think). Worked for me after that.
