20 amp breaker tripping

so went to use my Kobalt miter saw the other day (15amp) saw.

outlet is GFCI protected outlet not a gfci breaker. Square D brand breaker tandem 20 amp breaker with 12 gauge wire.

Saw works on a 15amp tandem SqD breaker perfectly fine with no issues.

So what should i be looking at for my issue?

And to note the GFCI outlet doesnt trip, the breaker itself will trip.
no other draws on the circuit when trying to use the saw.
And total outlets on the circuit are the dual GFCI outlet followed by 2 separate quads.

any help is welcome.

You're saying it normally works fine on a 15A breaker but it won't run a 20A breaker.

A GFI only trips on a ground fault leak. Over current won't trip them..... that's what the breaker is for. It sounds like you have a 20A breaker that may be a little sensitive. That's not uncommon. Try switching your saw to a different breaker.
