SyntaxError: invalid syntax

❌ Unable to enable JIT for UTM on device (redacted ID).
Could not connect to device (redacted ID). The process 'python3' returned unexpected output. SyntaxError: invalid syntax

This error occurs when i try to enable AltJit via GUI. Device is connected via USB-C, macOS 14.0, iPadOS 17.0.3, AltServer 1.7, pymobiledevice3 installed, python3 version is 3.10.13. Xcode as well as Xcode command line tools are also installed.

Start with /Applications/AltServer.app/Contents/MacOS/altjit and the pymobiledevice3 traceback, especially asyncio/base_events.py. Compare the Python interpreter used by altjit with the installed pymobiledevice3 environment, then reproduce the GUI activation path. Done means AltJIT can be enabled for the connected UTM device without the Python SyntaxError.
