Error when loading

[Trikkitt]

I've just installed the latest version of the Positron Studio.  However upon loading it (with dark theme) I get the same dialog box appearing again and again all down the screen "Cannot focus a disabled or invisible window".

Once it has displayed about 15 of these it starts showing runtime errors instead.  Nothing I can do gives me access to do anything because the windows appear faster than I can click OK on them.

Any ideas what is going on?
