SUMMARY
***
For some reason the latest nightly crashes when I save a file.
***

**Steps to reproduce**
Initially, I thought it might have to do with the file layers, but it even crashes on save when I start with this a plain template and initiate a save thereafter.



STEPS TO REPRODUCE
1. Create a new file
2. Hit save (Ctrl+S)

OBSERVED RESULT
After an initial pause of a few seconds, Krita closes. The document is not saved to disc, though it does appear under recent files in the taskbar. Clicking on the file prompts a message that the file is not available. 

SOFTWARE/OS VERSIONS
Windows: 10 version 19044
Qt Version: 5.12

ADDITIONAL INFORMATION
See attached log files.
And notice that I have plenty of disc space >160 GB on all discs.
