Cura 4.4.1 Fatal Error on Launch

Recommended Posts

Posted · Cura 4.4.1 Fatal Error on Launch

Like the title says, I'm getting the fatal error when I try to launch 4.4.1.  I've only been printing/using Cura for about a week, 4.4.1 was working for a few days and my prints were coming out good (i3 Mega).  Then, seemingly for no reason, everything started to fail.  I completed a print (final 2 bed leveling knobs), put those on the printer, and ever since then I can't get a skirt or the first layer to stick.  I heard some people resolved it by reverting Cura to defaults, so I went one step further and reinstalled Cura.  And that's when I started getting the fatal error.  Tried version 4.4.0, also got fatal error.  I'm able to run 15.04.6, which came with the printer, and 3.2.1 without errors.  I did update the printer's firmware in the first couple of days, had successful prints after that, but maybe that has something to do with the error.

Should I still do that if this has already been reported?  I'm pretty sure it has been a bunch of times.  Is there any workaround or should I just keep using 3.2.1?  4.4.1 was working before I reinstalled it, so it seems like it should be possible to get it working again...

If it's reported already, it does help if you post how you got your issue (full logs, specs, etc) in that issue as a comment. It gives us more info to work with and also increases the priority (since more people seem to suffer from the issue)
