I just updated from 2.0.x to 2.2.8 and while it launches, it seemingly fails to initialize. I toggled the developer tools on and there’s some very angry exceptions in the console.
RapidDataStore is not initialized and Cannot read property machineId of undefined. Both in bundle.js around line 140 or 163.
Let me know if you need more specifics - I’m not a JS dev though so you’ll have to point me to the right way to debug this.
I opened them via the View menu. It seems that the “Toggle Developer Tools” option is there while it’s initializing (and when mine got stuck), but it disappears once a tab opens.
