When I try to launch my application in test mode, it freezes on the splash screen.
Everything was working fine before this, and I haven't changed any code. The other version of the application, on which I had not worked for a few days, no longer works either, which excludes mishandling on my part.
The problem appeared on Opera GX. So I switched to Chrome, and everything was working fine, but a few hours later, the same thing suddenly happened.
My other applications work without problem.
In the console I can see a list of errors that I can't interpret...
