CoreScripts not loading in test server?

For some reason, a good number of my core modules fail to load whenever I open a test server using F7

Unsuccessful troubleshooting attempts/things I have tried: - deleting C:\Users\b\AppData\Local\Roblox (with and without closing my browser) - reinstalling studio - rebooting my computer - disabling and re-enabling FE

Judging from the lack of complaints I've seen about this problem on other forums, this seems to be a very uncommon studio bug; any help would be appreciated
