I can't open devtools after the update (in vscode). I reinstalled flutter and the vscode extensions, but the error (255) still persist.

I also tried this solution, but it still gives the same error (255).

$ flutter pub global activate devtools

I apologize in advance if this problem is trivial, I'm just new to flutter.

It seems duplicate of #2653.
