I used Themesflat Addons For Elementor to add some TF Tabs and other elements into my WP two weeks ago, it was working fine. But I maybe messed things up by changing the site theme, which deleted all of my TF widgets. I fixed this by reverting back to the old theme and then also backing up my website, but for some reason the TF widgets disappeared again even after they were fixed, I fixed it the same way again and then left it alone, but a few hours later, the widgets disappeared. I tried safe mode, reinstalling the plugins, deactivating the plugins, refreshing the theme, nothing worked. Can someone direct me towards a solution?

If you did all that to solve the problem then you have to do a different investigation such as deactivating other plugins to see if it is incompatibility
