Citation C525 (and SR-22) freezing

[airforce2]

I just acquired both the Torquesim Citation 525 and the SR-22.  I'm unable to fly either when equipped with the TDS Garmins, as the sim (XP 12.3.2) is intermittently going into a hard freeze (shows unresponsive in Windows, spinning circle etc)...these prolonged freezes last around 2-5 minutes, and then the sim comes out of the freeze and flies normally, usually just for a few minutes before repeating the problem.  The only way I've been able to complete a flight with the 525 is configured with just the UNS.  The Cirrus exhibits the same freezing, so the common denominator of the dual TDS Garmins leads me to suspect some sort of integration issue.

There's nothing unusual in the log before or after the freeze, and there's no crash report since the sim does eventually recover each time.

These two add-ons are the only ones I've used with dual GTNs active.  Is there a simple way to go to a single configuration, e.g. turn off or disable the second unit?

I'm running Win 11 25H2 on a fairly strong system--13900KS + 4090, not overclocked.  C525 is version 1.0.3, TDS gauge is 1.0.0.7.  I can fly the Hotstart Challenger and FF 767 for hours with no issues on the same machine.  There's no obvious system performance issue--I ran HWInfo monitored remotely from another machine and during the freezes there is no spike in temps or CPU/GPU load, and there's plenty of available RAM/VRAM.  I do not have the RXP plugin installed.

Any ideas on how to troubleshoot further would be appreciated.
