What happened to my extensions, tabs, workspaces

Hi. Today I upgraded to the latest version of Floorp. Before this, I had many tabs open on previous version, (too many to be honest), but at least some of them were organised in tab groups, although i can't remember the name of the tab group program i used. But after installing the new version and relaunching the program, everything seemed fine. But then because of an issue with not being able to see the tabs properly, i closed the program, when i reopened it again, everything had disappeared.
