PrusaSlicer 2.4.2+arm64 Gcode viewer error on Macos on first launch

PrusaSlicer 2.4.2+arm64

PrusaSlicer G-code Viewer 2.4.2+arm64

On Mac M1 

MacOS 12.4

Description:

Clicking on a gcode file to preview it in PrusaSlicer G-code Viewer opens the app, but fails to load the file, displaying this error:

Popup window title:

PrusaSlicer error

Popup window message:

PrusaSlicer has encountered an error

Unknown file format. Input file must have .stl, .obj, .amf(.xml) or .prusa extension

Clicking the OK button on the popup closes the popup.

I can view gcode file by then selecting File menu, Open Gcode option, and opening the gcode file (still inside the PrusaSlicer G-code Viewer app).

I have tried:

• restarting the laptop
• rebinding the default app for gcode files to PrusaSlicer
• uninstall and reinstalling latest PrusaSlicer

without resolving this issue.
