Getting this message in the console:

index-DQmWONGU.js:1 Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/html". Strict MIME type checking is enforced for module scripts per HTML spec.

So it does seem related.

I had the same - how could this happen if my opencode was running in a terminal for a long time without restarting?

The web UI is loaded from their servers - not your local machine.
