AI companion error

AI companion error, when I start to incorporate the Bluetooth extension tools this error appears.

After this error this other one appears. I don't know if it is a consequence of the first one or if it is actually the origin.

I would appreciate some suggestion.

Use this companion version

Remember: 2.73d1u is intended for ai2, not ai2-test and you will need the click the "Not Now" button.

And let us know, if it works for you now

Hello Miguel

Back-up your project to your computer before anything else.

To find out if the Sensor component is the problem, just delete it!

It would help to see your BLE Blocks too. From the top right-hand corner of App Inventor, temporarily change the language to English. Then right-mouse in the Blocks work area and select "Download Blocks as image".

Thank you very much for your quick response. I have tried the version that Tifòn has indicated and it has worked the first time. It no longer gives an error. I think that the second option is not necessary so I will continue with the project and if I have errors again I will do as you indicate and I will send you the information that you mention.
Regards
