Studios account wont load other accounts

My friend is on phone so he can only make games on studio lite and after a while of me copy and pasting what he builds, all of a sudden when I log into his account it loads and stays for a few seconds then closes. And not sure if this is related but when he made another account to keep working it got reported immediately and said content warning for sexual content.

A new issue. Due to me signing into the account on studios I am now unable to switch the account my Roblox studios is on, so when I open studios it closes before I can even do anything. so if there’s a fix I hope it dosent need studios to be on to work.
