Application launch did not return a valid pair nor a launch error on Xcode after build succeed

Question

I have a problem with Xcode when I try to run a fluter application on the emulator.

The build goes build succeed but then a pop-up appears saying Application launch for 'com.<My-app>' did not return a valid pid nor a launch error. No such process.

Before this error I got another error Flutter version unknown and I solved it with this command xcode-select --install.

These are the error details:

System Information

macOS Version 12.2.1 (Build 21D62)
Xcode 13.2.1 (19586) (Build 13C100)
Timestamp: 2022-03-11T08:56:32+01:00

Probably the problem is related also to the error that I got previously (Flutter version unknown) but it was a problem related to git.

Solution

It's an issue with authorization. Try this in the Terminal:

sudo DevToolsSecurity -enable

Started to have same issue, app keeps crashing, doesn't matter if it's xcode, flutter or testflight.

I solved it by reinstall flutter and Xcode.

If it is going to happen again I will try and post the result here. Now I have reinstall flutter and I have no problems!
