Cura 4.6.1 won't start

Posted · Cura 4.6.1 won't start

Hi everyone,

We use Ultimaker's at my work and today I wanted to upgrade Cura from 4.4.1 to 4.6.1. Unfortunately after having reinstalled Cura 4.4.1 and installed 4.6.1 it won't start, I get this error message:


I tried to reinstall Cura with no effect.

I also moved my old Cura 4.4.1 folder (wich I suppose contains my config files) with no effect.


I am not at all comfortable with these kind of erreor message and don't understand what it is trying to tell me... Can anyone help me?

    This does not seem to have anything to do with your (Cura) configuration. Cura crashes very early in the start sequence while trying to set up "sentry", which is ironically a tool for reporting crashes.


    I can probably fix the problem for you, but the method is an ugly hack, and it will probably cause the module to make and restore backups not work.


    Go to C:\Program Files\Ultimaker Cura 4.6\ and copy the file python35.zip to your desktop.

    Open the zipfile, and remove the folder named "sentry_sdk" from it.

    Move the zipfile back to its original place.
