In my non-default profile on my Macbook Air 2019 after I restart it (or even close it) all the windows in it except the one that I was last using disappear. This has happened twice. The first time, it was after restarting. Today the app would not open after multiple tries as it crashed before opening every time, and I just had to restart it and it happened again, no windows remaining except the one that I was last using. The image attached is after restarting my computer.
I open the profile and all my titled, saved windows are there. The image attached is before restarting my computer:
