Re: signal-desktop breaks after upgrading kdewallet from 5 to 6

Look at a file named ~/.config/Signal/config.json

There's a line there that says

   "safeStorageBackend": "kwallet5"

Change that to

   "safeStorageBackend": "kwallet6"

I think it was mentioned here at some point -- I wish I remembered who
to credit, because I didn't come up with this myself.

Good luck!
