I’d start with the cabin filter. Also make sure all cowl and AC drains are clear. Some people have water in the cabin filter. Could be moldy. after that you can try one of these to clean it

Yep, check cabin filter first. And see if things are wet.

You can also set things up to blow in recirculate with the filter out and spray Lysol in the filter opening. That stinks, too, but different.

Here’s the ac drain on the passenger side under the hood. Make sure it’s not plugged

Here’s a good write up for the cowl drains too

I got 90% of the smell gone with this. Bought another one to get the rest of the smell tackled.
