I installed Mac OS X Sequoia Beta 4 on an external disk.
Up until version 3 I had no problems using my apps developed with Flutter/Dart.
Unfortunately, however, after updating to Sequoia Beta 4, I encounter this “dart Application Not Responding” problem, although the apps on the Android and IOS simulator work correctly.
I tried to update but to no avail.
What can I do ?

I updated to the latest version of Flutter but the problem still remained
