Cura 4.12.1 Crashes

[gerthalberg]

When trying to use the plugin on Cura 4.12.1, Cura crashes.

[r00t4rd3d]

Its not working right for me either on Cura 4.12.1 and Windows 10 64bit. It gives me an error. Even though it says it could not save in the error box it does save the gcode file to the sdcard but when I stick it in the TFT35 it does not show a 3d preview, it only shows a generic icon.

[r00t4rd3d]

When I installed the newest plugin update I unzipped the files and copy/pasted the folders over the existing ones. I never deleted the old folders/files first. I started fresh and now it works.

Cura-dev here. I was just browsing through the crash reports (users can choose to 'send report' after a crash), and I found this in the error-trace, that I think might be related:

AttributeError: 'NoneType' object has no attribute 'scaled'
  File "C:\build\Cura\4.13-exe\build\inst\lib\python3.8\site-packages\cura\CuraApplication.py", line 1096, in event
  File "C:\build\Cura\4.13-exe\build\inst\lib\python3.8\site-packages\UM\Qt\QtApplication.py", line 482, in event

    img = Snapshot.snapshot(width = 200, height = 200).scaled(200,200,Qt.IgnoreAspectRatio, Qt.SmoothTransformation)

It was reported against 4.11.0, 4.12.1 and 4.13-BETA, by probably by separate users (anonymized of course, but we do get a sort of 'random' number corresponding to each user, which allows us to distinguish between crashes that happen a lot for a few people on the one hand, and those that happen not so often for many users).

I have the same error as mentioned by r00t and gert with Cura Ultimate 4.13.1 I have also noticed that, right click doesn't seem to work, and the bar (File, Edit, View, Settings, etc..) doesn't work either.

My crash log:

@aldaw It seems that this crash happens in a plugin called 'BigTree3D'. It should probably be reported to the developers of that plugin.
