Im getting Error CRITICAL : 'tuple' object does not support item assignment

[muengger]

I tried several times on an Raspi 5 (ubuntu) with two different cameras the tool but i always get the tuple error when the button toggleCrosshair is pressed or when the calibration is started. When i start calibration after safe controlpoint the printer fetch the head an go back to camera at this moment the tuple error occurs. the full print is : CRITICAL : Camera failed to retrieve data. CRITICAL : 'tuple' object does not support item assignment CRITICAL : Critical camera error. Please restart TAMV.

Hopefully anyone has an idea where the bug is. If i set a break point where these print functions are located it does not halt. Best Regards Thomas
