I found something interesting hear me out.
(this is currently a theory)
I found out that your school district uses this extention named "Endpoint Verfication" and they use it to see what bookmarks, files, websites you visited and use it to block sites the distrct chooses like Google Ai for example and when they sign into your school account the last sync they get is what they will see and which will also breaks the Endpoint helper. (which is what IT or your school distrits would use to )
and so if you use a extention remover like https://github.com/Blobby-Boi/ExtPrint3r you might be able to stop your school from manually syncing and from seeing more recent bookmarks and files in your computer meaning you can get away from principles seeing recent or old working exploits.
im also not 100% sure and so like i said this is currently a theory untill i test it. and i will also update this if i find more information.
