ERROR - POST-758856 - Failed handle request via 'RoomMembershipRestServlet' – when trying to leave room
See original GitHub issueDescription
I’m trying to leave the “Matrix Community→Servers/Hosting→Synapse Admins” room (!ehXvUhWNASUkSLvAGP:matrix.org) via one of my clients (doesn’t matter). All I get is “Internal server error” on the client, and

on the server (Synapse 1.64.0).
I tried clearing the client caches (didn’t help).
I’d expect to be able to leave the room under any circumstances.
Steps to reproduce
Just try to leave the room.
Homeserver
matrix.schildbach.de
Synapse Version
1.64.0
Installation Method
Docker image
Platform
Docker host is Ubuntu 22.04.1 all pretty much stock.

There’s a known bug where entries remain in
state_groups_stateafter a purge: https://github.com/matrix-org/synapse/issues/12821Tried this, but it does not seem to actually delete most of the entries in table
state_groups_state:The room does no longer exist on my home server (according to /_synapse/admin/v1/rooms), but almost all entries remain in the
state_groups_statetable.Any ideas on how I could help with this issue and/or how I can shrink my database?
