you probably have some scripts installed and they aren't updated.

Pop up? You're using some kind of userscript I assume? If you, you should probably either point out which userscript you use, or contact the script developer directly.

If you are using ESGST, then probably settings changed after an update and you need to change them manually.
If not, then post here: https://www.steamgifts.com/discussion/TDyzv/userscript-esgst-v6beta345-new-hidden-games-remover-users-stats-tables-sorter

Make sure the option 2.16 "Only enable for popups." in the settings menu is disabled.
