Failed to create IXPlaceholder Xcode 12.5

I am trying to launch my apps that were working earlier without any issue but after I updated Xcode & Simulator, I keep getting this error and none of my apps seem to be working. They build without issue but when trying to launch them, nothing happens and this error comes up.

Can anyone please help me with this?

    I changed to 11.4 and it worked fine. No other solution worked for me.
