Bitdefender prevent roblox from running? or roblox doest like bitdefender?

My sister wanna play roblox today but it seems that roblox keep force closing whenever bitdefender protection is running , this never happen before

upon closer inspection using process hacker roblox just terminate itself after i click play on the web, i cant even run the roblox player itself

i need to atleast add RobloxPlayerBeta.exe to Advance Threat Defense Exception list so that the roblox itself can run , which i dont trust scared that my sister may run into shady ****** on the roblox itself

iam using Bitdefender AV Plus (Build

Threat information update 13319705
