Cannot create BrowserWindow before app is ready (on macOS Monterey Beta)

[jandubois]

Running RD on macOS Monterey Public Beta (after fixing qemu issues: #518 (comment)) throws this error on startup:

A JavaScript error occurred in the main process
Uncaught Exception: Error: Cannot create BrowserWindow before app is ready
at L.nodeintegration (/Applications/Rancher Desktop.app/Contents/ Resources/app.asar/dist/app/ background.js:2:113101)
at L (/Applications/Rancher Desktop.app/ Contents/Resources/app.asar/dist/app/ background.js:2:113366)
at App. (/Applications/ Rancher Desktop.app/Contents/ Resources/app.asar/dist/app/ background.js:2:135146)
at App.emit (events.js:315:20)

The error can be ignored by clicking "Ok" and seems to have no other side effect, but re-appears on each startup.

I could not find this error in any of the log files; shouldn't it be logged as well?

I've now observed this dialog also on a macOS Big Sur 11.5.2 VM.
