Bug disappears window FaceTime on MacOS ARM M1 Venture 13.4.1 and another last too for incoming call.

The window disappears when an incoming call is received on FaceTime for MacOS. How can I return the window to answer the call and prevent the ring from being dropped?

Only "Quit" helped me and then called back.

This has gone on for years and through multiple updates.

I call someone, the call ends, then the window disappears, and the Window menu's options are all greyed out. You can't find the window in the dock, mission control, or anywhere. You have to restart the app to get the window back.

Sometimes, this glitch is entirely unacceptable to me as it causes crucial calls to be dropped, and I cannot answer them. Please fix this glitch once and for all. Several macOS updates have already resulted in FaceTime window disappearances during incoming calls.
