Needing help with engine/clutch issue on Brozz 250 (2020) 144 miles.

Ok, I have a 2020 Brozz that has 144 miles on it. It has been treated correctly leading up to now but has a possibly serious issue that I cannot figure out.

Setting up conditions of bike as current:

1. Changed shipping oil immediatrely to 20w-50 Valvoline Mcycle.
2. Clutch is adjusted correctly.
3. Being treated well during the engine break-in.
4. Jetted to run correctly (120/38/2 turns on fuel screw).
5. Clean new air filter
6. Throttle cable adjusted correctly.
7. Chain adjusted correctly.
8. Vaqlves set at 3/4 in/Ex

When started in gear with clutch pulled the bike will want to move forward slightly. With engine running or not and clutch pulled rolling the bike at a low speed makes a clunking/clank from the front sprocket area and you can feel resistance as it is moved forward with clutch pulled. Switching the gear to 2 with clutch pulled and the sound/resistance goes away. It is NOT a good sound as you can see.

I've attached a video - the video is done with the clutch pulled and the bike on a atv/mcycle lift so the back wheel can be moved. You can hear the issue then when I switch to 2 the issue immediately goes away. The engine does not seem to be turning over in the video - it's just very hard to turn the rear wheel.

Ideas, thoughts? It's been suggested it is a clutch/clutch basket issue and I'm about to remove the cover but have no idea what I'm looking for.

I should add that the bike seems to shift and ride ok but this is something that should not be there obviously.
