Formerly functioning program hanging on load or DAQmx physical channel creation, Labview 2025 Q3, Windows 11.

Not the first post I'd hoped to make, but if I can't get this program to run, not much point asking how to do trigger setups.

Using windows 11, LabVIEW 2025 Q3 (64-bit). 

I have a program that I've been making as a basic waveform generator and data logger for the NI USB-6259.

Three days ago, it was working, and communicating with the USB-6259. 

Now, after opening the program to the 'create project' and 'Open existing' splash interface, I can't load my programs, either my most recent or an earlier, simpler branch.
I can't open any of my files that use DAQmx. 

Specifically, with further testing, the moment I try to establish physical channels for a 'create channel'  module, the program hangs.

Rebooting the system resolved it, but this was still disconcerting and not something I've encountered previously.
