all my sessions are gone after macOS update

[moradiamr]

Describe the bug

all my sessions are gone.

Environment

I don't know if this is related or not but I deleted my Xcode and reinstalled command line tools without xcode and then
I updated my mac to macOs to 10.15.6, I turned on my MacBook, opened safari clicked on session-buddy and there was no sessions! all my sessions were gone.

I put all my applications in folders in lunchpad
but when I opened lunchpad after mac update I saw that session-buddy was not in any folder, it was like
it just installed!

where does session buddy saves it sessions? can I restore my sessions? they were really important to me

Desktop (please complete the following information):

• OS: 10.15.6
• Browser: safari
• Browser Version: 13.1.2
