Now that you have isolated the problem ie your computer and your setup, next logical step would be to re-install LabVIEW to see if that fixes the problem.
Let us know how it goes.
Two years ago (through my own foolishness), I was in a similar position where I "ruined" LabVIEW, try to remove and reinstall, didn't work. I actually did this on three machines, one Windows 7, and two Windows 10. The Windows 7 I could "fix". The Windows 10 machines I fixed by starting with the following three steps:
Backed up my files.
Inventoried my installed Software and Settings.
Reformatted my C: drive, reinstalled Windows, reinstalled Software, restored my files.
