Yep .... curving cut is worn out bar ... its not only the bar warps - but can be due to the chain groove widening and then chain cannot run 'upright' in it ...

If it’s never been used and the cutters don’t look too worn consider if the adjuster is inserted correctly. Perhaps try the bar other way up.
a small handheld saw like that needs a chain to have almost no play to be safe.
Perhaps the bin may be the better option if you value your hands.

And don't forget the bar lube.

The chain is 1/4" pitch which is the smallest chain produced. The slackness is a puzzle though. You'd think they'd supply the correct chain with the saw, so check again to see if it's been assembled incorrectly. Saws come with the bar dismounted to save space, so it may have been mis-assembled when new.

Many of the mini chainsaws do not have bar lube systems ... so its up to you to drip some 3in1 or similar on the chain.

One of the problems with these small saws - is the adjustor is fitted into plastic base ... if the saw is used too long - all gets hot and can distort that plastic.... or even cause as happened with one of mine - the base pin and screw adjustor to be misaligned ... this then can lead to lack of full adjustment ...

The chain hasn't come off the drive sprocket has it?

Chain oil is very viscous. 3 in 1 would be too light. If you don't have chain oil, maybe gear oil would be a good substitute. Or at a pinch, engine oil.
That's a possibility. OP says they've been in there and adjusted it to the max, so they'd likely have seen if it was off the sprocket. Worth checking though, could have slipped off when the cover was being replaced.

Agreed - but any oil is soon gone if there's no feed ...
Chain slipped of sprocket - if it drops behind sprocket - it feels like its still on - but of course is then very slack .. not an uncommon event if user is fitting chain with saw on its side ...
