Problem in opening a second instance of SU

To open SU 2024, I signed out of SU 2022.

Then, after finishing with my test with SU 2024, I wanted to reopen SU 2022.

This is what I see.

I restarted my Macbook Pro and now, when I try to start SU 2022, I see this.

The button that is offering me to relaunch the web browser doesn’t work.
