¶ Internal configuration errors
This is most likely the case when you upgrade from a version lower than 4.5.0, and you can solve the problem by resetting the configurations.
Before resetting, you could back up your Laser and CNC configurations if needed. The printing configurations are incompatible with v4.5.0 and above versions due to Engine upgrades.
To reset the configurations:
