I use a real device (XIAOMI 11 Lite 5G) with Android 13.
MIT App Inventor 2 Version 2.65u installed.
I'll try to reinstall companion.
Reinstalling the Companion App did not bring any improvement.
The only way that works for me is to create the apk file.
Unfortunately not very cheap for tests.
Is there another way to further localize the error?

Test in a different project, maybe current project is corrupted.
I tried it with different projects.
It works without an extension.
As soon as I move an extension to the mobile image in the designer, the AI companion and USB connection crashes.
Companion not working either?
I will test the offline version and then report.
Companion doesn't work either.
Either it stops at 95% or the same error message appears.
Tested with AI2Offline and it works there.
There I use version 4.64 and the latest "AI2 Offline Companion.apk"
So there seems to be a problem with MIT Appinventor after all.
Apparently not for all users.
I moved your question / thread into a new topic (as it is not related to SAF).
Maybe you want to modify the topic.
Thanks Anke.
That's a good idea.
Did you test it on another device?
I tested it with a Pocophone F1.
The same error.
Other cell phones are not available to me.

I suggest using a more modern emulator from
and dragging a fresh current Companion into it if needed.
Sorry I don't understand your answer.
I use version 2.65u on the smartphone.
Isn't this up to date?
Frank
Your smartphone is up to date.
Your emulator might not be up to date., in its Companion or its O/S.
The stock MIT emulator can't run some projects.
Can you please send me a link to the current emulator.
If possible a 32bit version.
Thank you very much.
Frank
This is a more recent emulator
but it needs a sideload of the latest Companion:
http://appinventor.mit.edu/ai2/ReleaseNotes.html
see FAQ Section: Companion and Emulator
for other emulator options.
I think this might be an issue with the USB connection, but I need to investigate.
