Suddenly I can't play most games in 3 D anymore

[mcc]

Hello,
I installed 3D Fix Manager some days ago & all games were working fine.
Suddenly most games stopped working in 3D mode.

I can only sill play Doom - Eternal & RE - Revelations 2 in 3D.
Bloody Spell, Grim Dawn of Just Cause 4 don't work in 3D anymore.
ReCore does only show a pink screen.

My monitor (ASUS VGHVG278H) shows that 3D is activated but there is no stereo 3D in the games.

I also noticed that the 3D-Test in Nvidia CP does not work anymore.
The Medical Test picture does also not work anymore.
When I try to start it, I get the following Geforce 3D Vision Setup Wizard Errors:
"Error in StereoCPLAPI,
Settings->setDefaultStartupMode() returned false."

&

"Exception in StereoCPLAPI,
in Settings->setDefaultStartupMode()."

I already reinstalled Nvidia drivers & 3D Fix Manager but it did not change anything.

I don't understand why I still can play some games.
It does not make any sense!?

I hope that someone can help me.

EDIT:
I solved most of the problems by reinstalling the 452.06 driver.
Most games do work again in 3D but the 3D Stereo will only be activated when I press CTRL+T.

ReCore will still show a pink screen, though.

Yes, windows up date will auto update your display driver. There's a way off keeping it from doing it. There's a post on here....I'll try to find it. Normally 3Dfix manager will let you reinstall 452.06 and fix it. But, I recommend using display driver cleaner then reinstalling the last working driver.

I am also having lots of problems. Even after installing 425.31 Driver, 3d just does not seem to want to kick in on any game.
I run the 3d test, and it seems to be working. However any game I try, the light on my emitter is green, but 3d does not seem to want to kick in..
Tried different usb and display ports.. No luck (2080 ti) Asus PG278Q.
Almost wondering if I should try a new monitor.
Tried starting games with 3D fix manager. Nothing is working.
Tried DDU recently.. Anyone getting 3d to work and stay working? I was able to get 3d working a while ago with the newer drivers and the hack, however windows keeps updating and I have to go through this every time I restart.
That's why I was hoping to get 425.31 working. Much easier to just install that and go.

Windows did not update the drivers.
If this was the case, all the games would not work in 3D.

I can now play all of my games in 3D - except 4 ReCore.
This game simply does not work anymore & when I start the game I get a pink screen & sound playing in the background.

The other day it was working flawlessly - just like the other games.
I also did not have to activate 3D mode manually by pressing Ctrl+T.
