Use TinyDB to check, from which screen you are coming from and only open Main Screen if you are not already coming from Main Screen

Alternatively use the manager screen method and just close the main screen to be back in Screen1... you have to test this in the apk file... why? See the notes here App Inventor Tutorials and Examples: Manager Screen | Pura Vida Apps

You cannot open and close Screen1. Screen1 must be in the background all the time. Opening and closing other pages, but never open and close Screen1.

@Taifun You're right, you can close screen 1, but not closing it will solve the problem here. The problem is that after closing Screen1 and reopening screen1, initialize blocks will execute. In these blocks there is an automatic jump to Screen1, so Screen1 cannot be opened. The solution will be to not close screen1, keep it in the background.

Try it:

Blocks in Screen1:

Blocks in Screen2:
