PyQt cannot execute a minizinc process

Question

I am trying to run minizinc from a pyqt application. Instead of producing a result it will just return ====ERROR=== What is happening here

I have tried to use pythons minizinc package as well as simply calling the minizinc cli but neither works. For example if I run subprocess.run(["minizinc", "test.mzn"]) from a separate clean python file I get a correct result, however if I run:

self.p = QProcess()
self.p.start("minizinc", ["test.mzn"])

from my PyQt class I get ====ERROR====

Answer 1

It appears to be a bug within pyqt6. After switching my code to PySide everything works perfectly
