Anyone else have or had A/C issues with their Lexus?

I bought a 2021 Lexus is350 f sport a week ago and the A/C was working just fine then all of a sudden it won’t blow cool air? I check the refrigerant gauge and filled it as needed but no luck. Any ideas of what could cause this would help a lot to avoid spending a shit ton of money on a mechanic but if I have to I will.
