Multiclienting- 2nd Client Crashes

When I multiclient I usually use the main client on full screen and the 2nd client on window mode.
Lately the 2nd client begun to close randomly. no error would appear.
It happens totally randomly BUT it happens a lot when the character on the other client is lvling.
I know it probably happens because I switch between window mode and full screen.
One guy suggested downloading the IMG setup but unfortunately it didn't work

Windows 11~

Thanks♥

 

Ive had the same thing happen on wz files. What did not work with the img files?

 

IMG setup didn’t solve it for me.

 

Oh I thought something was wrong with the download.

so when you multiclient with both clients in window mode you are fine and when you use window mode on one and full screen on the other the window mode one crashes without any error right?

 

Exactly

 

Anything? Anyone?
