Unity throws tons of exceptions non stop when there is a single null reference issue.

Why does unity sometimes throws so many and make the program slows down duo to the massive amount of logs instead of just throwing one?

 

If the error is in your update function, then it will repeat every frame.

 

It is not there, If I simple put a condition that if it is null just print something and return, it will print only once.

 

Would need to see your code to provide more help.
