I'm having this same issue. Using chat.iridescent.nz, the community-hosted Element-web app for matrix.iridescent.nz, I created a new session, and verified it from my Android session. I'm able to access all my rooms, but in all the encrypted rooms (including DMs), all previous messages say "unable to decrypt" (including my own).

It's not out of the question that there's some user error involved. But I've been using Matrix for about 5 years and I've tried everything I can think of, done some web searching, and followed various advice on joinmatrix.org etc. Nothing has worked so far.

When the problem last happened I was using LibreWolf 130.0-3, on Fedora 40 Mate-Compiz. Today I upgraded to LibreWolf 130.0.1-1, from the Fedora repos. If there's any more info I can supply to help you track down the bug, please let me know.
