This may be a niche solution to this issue, but it was the only thing that worked for me (yes, I tried every solution in this thread).
If you happen to have a stream deck, you can use the "Windows Mover" plugin by bar raider to recover a window from anywhere. Simply select the lost window from the drop down list inside of the plugin, leave the window coordinates set to (0,0) and then press the button on the stream deck. This will move the window to the top left corner of your primary monitor.
Hope this helps someone.
