Haven’t you seen this error before & not known what it means?

Based on my observations, I have created a list of the Permission (aka. Security Context) Levels in Studio.

Please refer to the solution for an accurate answer.

I was completely incorrect in determining the Permission levels.

Notes
  • That error at the start of the post is a plugin trying to class check RobloxPluginGuiService through Selection.

I have very little knowledge on this but I tried to help out on this post
Security Context Link
found this link from roblox.fandom that talks about security context and I think this might help out

By using the deprecated printidentity() on that page:

  • ServerScripts & LocalScripts are both 2
  • The page says plugins run at 6 and the command bar runs at 5, but from using printidentity() I got my original results.

I will edit my post accordingly.

This is more than incorrect, Studio runs with two identity systems: Permissions and Identity Level, neither of which have any discernible pattern.

There are 8 identity levels within Studio, each of which can be read through the deprecated function printidentity

Script Identify itself is an unsigned 8 bit integer that can have a value between 0 and 255, however only 1 through 8 have any set permissions.

Identities 1 and 8 are unused, however 8 may be the identity used by a secret internal tool that will not be named, you can find out what SECRET TOOL is with some clever googling

Identity 3 is scripts running under an approved Roblox game

Its also worth noting that CoreScripts run at identity 7 and executors run at identity 6, the same as Studio’s core plugins

To further secure Studio, each of these identities also run within their own enclosed Luau VMs
