Custom Resolution Utility (CRU)

Heya, registered here to make this post specifically.

First of all, thanks for this amazing utility! I've however encountered a weird issue with it:

I have a 3060Ti, using 1 Display Port to connect to my main PC screen (LC Power M25-FHD-144, 144Hz per spec), and using the HDMI port for my second screen (HP 23CW, 60Hz per spec). Currently on Windows 10 22H2 with nvidia 552.44 drivers. Using your tool allowed (and still does) me to use my main PC screen @240Hz and 10-bit mode, and everything works fine, gsync and all. However, when I use CRU to make any kind of adjustments to my settings, and I try to reboot my pc my screen goes blank and the system is not responsive, I have to restart it.

I have noticed that if I physically unplug my second display (the HDMI HP one), the problem goes away and everything works fine. I've tried different driver versions (newer ones), and they all acted the same.

So overall, it all works until I try to restart my PC, at which point it can't properly boot into windows for whatever reason (it does work on the 2nd boot, power off and on via the power button), but works fine if I disconnect the 2nd display. It also works fine if I add the custom refresh rate via nVidia control panel, but I cannot set 10-bit without using CRU, at which point I get the same issue.

I've tried to troubleshoot myself, using CRU only to add 240Hz, or only to add 10-bit, but it would not reboot properly either way. If I use nVidia and set 240Hz 8-bit, it reboots fine. If I unplug my 2nd display it also reboots fine.

I hope I got my point across and that there's something simple I'm just overlooking. Thanks!
