Error page when attempting to access decal tab on develop page

I get this error page both on Chrome and Firefox. It happens on two different accounts (my main account and an alternate account), and I’ve tried clearing my cache/cookies and that didn’t help either. I don’t have any plugins on Firefox that affects something purely on the develop page (The only thing I have changes the color of the topbar and sidebar on all pages)

It’s being really weird too – sometimes it errors when I go to the develop page, but other times only on the model/decal tabs.

Edit: It’s erroring on the default studio landing page too (develop/ide or something)
