delete the virus script and try to disable the plugins that @AC_Starmarine mentioned, and try again
even tho i think model resize plugin is safe but idk about the other one.
Its trying to bring a malicious model into your game. You best just reinstall studio because if this keeps appearing in all scripts then thats your best bet. Then check for malicious models, etc.
Note that it might also be other people in your team create. So you need to check if they as well have a virus. Another thing if you go to settings you can check what plugins have the permission to modify code:
It will say “Script Injection” along other things or “No Permissions Requested” if it is completely safe (since it can’t inject scripts)
I tried re-installing and uninstalling plugins, but that didn’t work- Script Injection Detectuin helped a ton! I ended up finding the plugin- It’s been slapped back to where it came from! I’ve reported the plugin and posted a comment.
