Dual Box Shuts Down 2nd Window

I haven't had this problem until now. Windows update farked my PC and I had to reinstall windows with save files option. Now, if I open account 1 and it loads, as soon as I click the windower button to open the 2nd account, the 1st shuts down. I have the latest GPU drivers for 3090ti. I have both pol.exe and windower set to run as admin on all users.

Did you turn off dimming of UAC?

You can also try dgVoodoo (or another DX proxy) which may help.

Ya sorry meant to put that in my OP, my UAC us completely off
