Hi and welcome to devnet,

Which version of Qt ?
Which version of macOS ?
Which version of Xcode ?
How did you install Qt ?
Does it happen with a minimal application ?

@SGaist
Thank you for your reply.

QT：5.15.2；
QT Creator：7.0.0
macOS：12.3.1
Xcode：13.3.1（same crash to 12.5, 11.7）
Install QT by qt-unified-macOS-x64-4.3.0-1-online.dmg

It worked fine three days ago, but started reporting this error yesterday. The same code compiles and works fine on other macbook

SGaist

Does it also happens with a default application ?
How does your current setup differ from the other machines where it works ?

@SGaist
The sample project reported no errors. and I rolled back my project to the first commit and found the same error.
It surprised me.

I suspect that some cache configuration is affecting
So I created a new project, copied all the files to the new project, and miraculously, the program ran successfully

misumisu

Well, I modified my app BundleID and it ran successfully. I don't know what cache configuration is in effect

whitebrow

I have the same problem.
My solution is:

bash: remove '~/Library/Preferences/com.xxx.xxxx.plist'
bash: killall -u $USER cfprefsd
