Ultimaker Cura might crash when opening a file, when another application called 'Chitubox' is installed. This has started occurring since Ultimaker Cura 4.9, as there is an incompatibility caused by the two programs. There are two options to prevent Ultimaker Cura from crashing:
- Uninstall Chitubox completely and continue using Ultimaker Cura
- Uninstall the Chitubox thumbnail preview, by following these steps:
- Open cmd with administrator rights
- Enter the command: regsvr32 /u "C:\Program Files\<path to CHITUBOX_Thumbnail.dll>"
- Restart the resource manager
If this does not resolve your issue, please submit a request to get support from the Ultimaker Cura team.
