I've always had issues with Windows not staying in place after monitors are turned off, especially when it's a mix of Display Port and HDMI. I have 3 monitors (actually 3 4k TVs). I am on Win10Pro - not sure how much better Win11 is.  This program has been absolutely GREAT for me. Works like a charm. All Windows are ALWAYS where I left them.  See this link (note: MajorGeeks is a well-known and respected site): https://www.majorgeeks.com/files/details/persistentwindows.html
