      If it was fine previously and you recently removed the derailleur it could be that the b limit screw/plate is not sitting on the little tab on the hanger

      Lookup how to size your chain, it’s pretty straightforward and there are alot of guides

      if it’s not your b screw, it’s your chain being toooo long. maybe try just pushing your bscrew to extremes, if it continues even at that extreme shorten the chain

      Looks too long, but you wanna double check sizing and everything with your derailleur spec and also with the rear suspension bottomed out. Park tool has excellent videos on chain sizing I reference all the time when I’m not sure. Basically if you size it for a bottom out suspension while also in the biggest cog the chain could snap if it’s too short. So double check that too, it basically looks too long though from here.

      that chain is way past what the b screw can fix, you can see it’s drooping even on the big cog. pull it off and size it properly, wrapping around the biggest cog and big ring with no derailleur.

      I mean its a good length if you want to drag your chain down the trail after every little bump.
      Ideally you want the chain to have 1-2 links in your lowest gear, just enough to get on/off the gear. Then the derailleur will keep the chain under tension in the highest gear.
      In general, the longer your derailleur cage, the wider range you can accommodate in the cassette. If you can’t find a length in which the chain fits over the lowest gear and stays tight in highest, then you need to change your cassette or derailleur.
      In actuality, you’ll be using your highest gears more than your lowest most of the time on trial/enduro riding.
