Trading got disabled after i renounced ownership

I deployed this contract, everything was working fine but suddenly trading got disabled. As you can see in the transactions I didn't call the function and it all happened after I renounced ownership. Would love some help since some people invested in my token and I don't want to scam them.

Our have already renounced ownership...
The only thing you can do now is to create a wrapped version of the token

I know, but I was wondering what caused trading to got disabled, I don't seem to find a malicious function in the contract.

Would review the contract but not immediately
