the problem still happening, this error log is captured from emulator and usb, from wifi the app not doing anything after loading screen ends.
This error start to happen in very of my big proyects.
With new proyects works fine.

I see other topics with similar issues, talks about updates, i tried to update app and the issue stills.
tried to eliminate all extensions, not work.

But the problem is that not longer works my big proyect that i working one year.

every extension stop working in companion. Stop working with QR too, also with new projects.
very bad week for app inventor. Too many projects are in jeopardy.

Sorry, but your statement is incorrect
There might be some extensions, which need an update...

so if you find an extension, which does not work anymore after the sdk34 update it would be nice, if you could report that in the corresponding extension thread.

you are right, i found after test that the problem is the companion. Many extensions works with usb.
Today i test again many projects with qr in companion and still not load.
