Installation Home Assistant OS

I can no longer access he supervisor page on my Raspberry Pi Hass. I’ve restarted, cleared browser cache, tried 3 different browsers. In my Safari/Chrome Web console I have an error:

Unhandled Promise Rejection: TypeError: this.supervisor.localize is not a function. (In 'this.supervisor.localize("panel.dashboard")', 'this.supervisor.localize' is undefined)
performUpdate — entrypoint.b954f17a.js:47458
(anonymous function) — entrypoint.b954f17a.js:47458
asyncFunctionResume
(anonymous function)
promiseReactionJobWithoutPromise
Selected Element

Not sure what to do next?

I had the same issue, turns out supervisor updated itself to a beta version but didn’t update HA Core - running ha core update from the terminal addon I had installed (or the actual device console) fixed it.
