I found the problem guys, its not the extensions, its not the adblocker, its the VPN. Yeah specifically the VPN is preventing roblox from loading up, also if i have to do all the thing below in order to load up a game, than opera isnt worth it:
Disable all extensions
Disable the ad-blocker
Reset settings to default
Reset flags to default
Create a clean profile folder/directory
If the problem is with a web page, check if it works with other browsers, specially Chromium based ones
Check if your OS is up to date
theese are things that arnt worth the trouble and they should tried to be fixed in my opinion
