Add-Ons not loading

Since a couple of days my Add-On page isn’t loading anymore (blank screen) and also all add-ons are not loading (also blank screen).
I am running on a raspberry pi 5 and tried restarting multiple times (also with unplugging the pi). Also tried restarting in safe mode. I also tried loading a backup from 3 days ago. Nothing of these things worked.

When I check out the log, I see the following error:
Logger: homeassistant.components.hassio.http
Source: components/hassio/http.py:235
integration: Home Assistant Supervisor (documentation, issues)
First occurred: 17:36:54 (1 occurrence)
Last logged: 17:36:54

Client error on api app/frontend_latest/entrypoint.1e251476306cafd4.js request 400, message: Can not decode content-encoding: br

What should I do?
I have access to the pi, but I don’t have a micro hdmi cable at hand to connect a monitor to it.

Have you tried restarting Home Assistant or clearing your browser cache / trying a different browser.
Old data in the cache sometimes causes symptoms like you describe.

Yes I have tried restarting HA: I did “Restart Home Assistant”, “Reboot Home Assistant” and disconnecting my raspberry pi from power, waiting a bit and plugging it back in.

I also deleted my browser cache, tried a different browser (edge, chrome, safari) and tried a different device (laptop, tablet and phone).

I didn’t change anything and it started working again. But my remote access through nabu casa stopped working.
