Track IR not working anymore, CTD when using it

[Leif]

Good day,

I used to play SimRail using Track IR for a long time without any problems. After a long pause I recognized today that some people including me are having problems with Track IR at the moment. The game does not respond to head movements. When turning the ingame option regarding TrackIR off and on again the game crashes to desktop. Also restarting the TrackIR software does not fix it. In the log file I found the following path:

It seems to be a problem regarding only newer Track IR versions. I have the newest version (5.5.3) installed. Could you please investigate into this?

Edit: I also deinstalled Track IR and the driver. Unplugged it and replugged it. Installed older versions like 5.4 and it is still not working. It seem it is not recognizing SimRail as supported game and Simrail does always crash when loading into a train with Track IR enabled.
