Resource limit exceeded error on new account.

Hi, I made new account a few days ago to use the free tier. I only trained one simple model on sagemaker studio. But now when I try to training another simple model I get this error.

An error occurred (ResourceLimitExceeded) when calling the CreateTrainingJob operation: Resource limits for this account have been exceeded. Please contact Customer Support for assistance.

I can't understand which resource limit this error is referring to. How I check how much of my resources I have remaining?
