Question about Husqvarna 445 18" 45.7 Cc Chainsaw W/warranty
It may be running very rich, make sure the air filter is clean, if ok. check the spark arrestor in the muffler outlet ( if fitted ) has not carboned up, if ok, check the exhaust port is not blocked with carbon.

I don't think this has the detail you need.
If it were me I'd visit my friendly neighborhood Husky chainsaw seller (not Big Box Store) and ask to look at the clutch cover with the brake installed (take a camera). I'd probably ask for a quote for their repair too. HTH
Your model is no longer sold. The seller will know what model replaced it and may be willing to explain the repair procedure for your saw you. Take the cover and loose parts with you.

These machines have had issues with main bearing cages breaking up, this it turn scores the piston and snags the ring in, if there is a good spark and the plug is getting wet i woud whip the muffler off and take a look at the piston through the exhaust port.

Testimonial: "Took to dealer. in five minutes they showed me the piston through the exhaust port. PISTON SCORED. Blamed thing hasn't been used 20/30 hours. Thanks."
SOURCE: I have owned my Model
It sounds like a warranty issue, up at the engine you have a centrifugal clutch bolted to the flywheel, as the engine speeds up the clutch expands and engages with the drum, this in turn rotates ans turns a flexible shaft within the tube, this engages into the gear box and turns the gears that turns the head, so i would say the flexible shaft is either slipping in the drum, or the tube or gearbox has moved out board so is now too short to engage into the drum.
