Cause of LabVIEW Crashes

[l3h]

I'm working with a PXIe-7820 device, so I have a host VI and a FPGA VI. Yesterday, I made a save on my personal PC to the host VI, pushed it to the source control system and went to the lab (I work on my personal PC and a lab PC). When I got there, LabVIEW would consistently crash if I try to open the host VI with no error code (i.e. the host VI would just open as a white screen and the top ribbon would go to 'Not Responding') even when I let it run for over 30 mins. The same issue is happening on both PCs now. 

I immediately tried to check my previous commits and now I have the same issue being unable to open the host VI when I was successfully able to run testing on it the last two months. I tried resetting the PCs, repairing the installs, reinstalling the instrument drivers and I have a tech support case active but we have been unable to isolate the issue. 

A new problem now is that LabVIEW consistently crashes (dummy project picture attached) when I try to add a control to the 'resource name' input on the 'Open FPGA VI Reference' function, so I'm unable to create a new host VI. Or at least unable to do it the way that I know and anyway, I'd like to recover the work that I spent a lot of time on. 

Has anyone encountered an error like this?

If the problem is clear, does anyone have any ideas for a solution?

Notes:

• My employer does not allow the source project files to be shared
• I got impatient and am currently uninstalling everything and planning on reinstalling, but I'd like to understand the problem so it doesn't repeat
• System Information: 
  • Windows 10 - LabVIEW 2023 Q3 (64-bit) and all the required, compatible drivers required for the PXIe target

Only other thing I would have tried is clearing the compiled object cash.

Closing out of LabVIEW, reverting source to something that previously worked, and clearing compiled object cash before opening the project again. I'm might also try a mass compile. I'm not sure if mass compile does much if your source is separated from compiled code and you delete the cache but it can sometimes pick up insane objects which can do strange things sometimes.
