PulseView crashes under windows 10 while loading, if previously imported and opened capture-log files (*.vcd in my case) moved elsewhere, renamed or deleted.
Restoring files to "expected state" (moving previous location etc.) solves the problem.

I can't reproduce this on Win10 anymore as of today. Can you please try and let me know if this issue still exists for you?
