I expect most of your problem is a bad appimage. The real 1.0.3 appimage (available on Fritzing.org) is fritzing-1.0.3-l1995-a7811ba0-qt6.AppImage your appimage Version 1.0.3 (b1.0.2rc2-247-ga7811ba0 2024-05-30) 64 [Qt 6.5.3] AppImage appears...

As a data point it appears to work fine on 0.9.10 on Win10  so this looks to be either Mac specific or your configuration specific.
