Hi, Could you please Right click > Inspect > Console for any error?

[xobs]

Sure. It says:

Uncaught (in promise) TypeError: Cannot read properties of null (reading 'nextBatch')

In the console, could you go to Application and try clearing "Local storage" and deleting "IndexedDB" entries.

Seems like you also had this in 3.2.1 as reported in https://github.com/cinnyapp/cinny/issues/1764

[xobs]

Yes, like before, that works around the issue. The error is different, so it didn't show up when I searched for fixes.

That means the underlying problem is still there.

[kfiven]

well, underlying problem is not known, and that is what I am trying to find. Did clearing those storage fix the issue? Because I have cinny working well on windows. Seems there are something specific happening for you.

[xobs]

Yes, clearning storage (by going to Application, then Storage on the left, then "Clear site data" on the right) fixed it so that it now starts up and lets me log in.

This probably seems like similar to https://github.com/element-hq/element-web/issues/27520
