I can confirm i had this same issue, apparently AVG was flagging roblox as malware, and i couldn’t get it fixed, even sfter whitelistin robkox. i had to uninstall avg, but luckily it wasnt essential, so i will just have to stick with windows defender for now
I would recommend whitelisting Roblox, as it may be being flagged by the avg.
Thank you for the report. We confirmed that recent changes to AVG’s software require our attention. Our team will begin making adjustments to ensure continued compatibility.
