Cura 20.01 won't go past splash screen.

General Software

Hi Guys,

Microsoft Surface Pro 4 (brand new fresh install, fully patched).

Cura splash screen runs, i get the wizard, click finish then nothing.

Pythonw.exe still running in task manager. Kill it, try Cura again, same as above but no wizard.

Tried Cura 15, no issues at all.

To Add the the above, I only get the output_log messages when i run the cura.bat file from commandline and terminate the batch file when nothing displays.
Doesn’t seem to generate anything when run from the shortcut.

Same behaviour in 19.12, 19.08, 18.03.

17.10 works perfectly fine.

Looks like https://code.alephobjects.com/T434 is describing my issue.
