Crash when selecting "Create Variables"

[LambdaKnight]

If I start with a completely blank project, create a Library, then right-click on the library and select "Create Variables...", LabVIEW crashes to desktop. It also does this with "Create Bound Variables...". It does not crash if I use right-click -> New -> Variable. Any idea what might be causing this?

I'm on LabVIEW 21.0.1f2 (64-bit) on Windows 10 Pro (10.0.19042)

Hi  LambdaKnight, 

Can you attach some screenshots of crashed window for a clearer understanding?

[LambdaKnight]

Sure. Not sure how much help it'll be. Click on the highlighted option and the entire application crashes. Nothing else except for the Windows crash dialog. The Event Viewer has this:

Because you "hid your code" (you didn't attach the Project, so we can't open the Project file to see what you covered up with the Dropdown), I'm not certain I reproduced what you tried to do.  I created a blank Project, dropped a blank Library, right-clicked and said "Create Variables", and got a Batch Variable Creation screen.  No crash.

I was running LabVIEW 2021 SP1 (32-bit), not (64-bit).  

Is this a recent installation of LabVIEW 2021?  Is there a possibility of a mis-install?

Nothing was covered up by the drop-down. You did exactly what I did. That you're not getting a crash does seem to indicate it is something wrong with my environment. I shall look in to it more.

[LambdaKnight]

I removed MVEProvider.mxx from the installation and then ran a repair on LabVIEW to see if maybe that would fix it. It did not. Still crashes. LabVIEW 2022 Q3 doesn't crash when I do the same thing.

[l.hovs]

Then I think either you should use LabVIEW 2022 Q3 for avoiding any crashes, or uninstall and reinstall your drivers if you want to stay in 2021 version.
