Unable to "publish/publish as" due to "Attempted to upload invalid content"

The past few days, when trying to publish to a place besides the one I’m currently editing, I get this error constantly:
RobloxStudioBeta_g3IIMfxDJq

Retry does not work, and gives this window each time:

The publishing process seems to hang for much longer than usual when this happens. I can’t get it to happen consistently outside of random windows of time throughout the day.

Expected behavior

I expect the game to publish normally, whether I’m using Publish or Publish As.

I’m not sure of it myself, but pretty much roblox studio also has like a moderation tool that would check if place has some Inaproppirate content or content used for Backdoors, exploits etc… Again, I’m not sure of it itself, but you should check if something inside your game isn’t Inaproppirately named like scripts, models etc.

Hope this helps.
