Yep, it all started there. It will not allow Roblox to launch despite adding:
RobloxPlayerLauncher.exe
RobloxPlayerBeta.exe
RobloxPlayerInstaller.exe
ALL THREE of them to the exclusions.
I dug through Windows defender as well incase that was the issue.
I looked into the logs of both and neither had mentioned stopping Roblox from running.
I tried different AMD drivers, reinstalling Roblox, reinstalling bitdefender, checking regedit for forcing stack protection on etc.
Regardless, I uninstalled BitDefender and it magically launched like it used to and my PC sped up about 20 percent faster. Sorry to say it, I thought this would be the product for me... guess not.
