bug: 🐛 Failed to decrypt the data: data authentication failure

[WinsDominoes]

Bug Report: Failed to decrypt the data: data authentication failure

Describe the bug

It seems to be an error with decrypting the data - not sure why it happened randomly, which after that crashes the bridge.

To Reproduce

Steps to reproduce the behavior:

• I am unsure why this happened as it randomly occurred today. My friend told me that it might have been due to a random group chat that sent a message which caused everything to break.

Expected behavior

A clear and concise description of what you expected to happen.

Additional context

My sincere apologies due to the lack of details in this bug report, but that is sadly all the information I could gather.

It seems to still happen after resetting the database, i.e. deleting the database completely, restarting the bridge, and re-login - the issue still persists. -_-

Something to note is that we don't have E2E encryption on for Matrix, so idk if it relates at all

[highesttt]

Thanks for the bug report, I'll look into it today, see what could have changed

EDIT:

I dont think this is related

I've went ahead and fixed the crash and added extra logs on this branch, if you're willing to reproduce the bug and send the new logs that would be great!
