Lost my emails

Hi, thanks for considering my problem, I'm not as sharp as I used to be and can't quite think these things through anymore. Here's the situation: I installed TB on a portable ssd and use it on two different Windows 11 computers. I would click on the TB shortcut and a window would open asking me to pick a profile. I would pick my profile and see all of my emails. Worked well that way for several months. This morning I opened TB, picked my profile and it went straight to the account setup screen. I shut it down and tried it on the other computer and got the same thing. I can see my profile still on the portable drive and the pointer in the profiles.ini file in %appdata% area on each computer still points to it. How can I fix this so I can see my emails again?
