He is a former president, one of two candidates in this year's election and a potential candidate to become the 47th president of the United States. That means he is not a criminal and would not face any legal problems even if he cannot become president. If he were a criminal, he would not be eligible to run and President Biden has also sought to put him in prison. You are an American and I know you understand that better than anyone, but you stubbornly deny it. So even if there were more debate, there would be no final result.
You really should do a little research before you post.
First of all, Trump is in fact a convicted criminal, found guilt by a jury of his peers:

This case was brought in the state of New York, and it had nothing whatsoever to do with President Biden. Trump defrauded a bank and got caught, which is why he was found guilty.
Second, there is nothing in the US Constitution that forbids a convicted criminal from running for, or obtaining the US presidency:
