i was out at a new park and the bike was completely fine , but on my way home i noticed i was losing speed very fast and i couldn’t coast at all yet i carried on. when i got to curb i bunny hoped onto it and i heard a snap. i pushed the bike further as my pedals did nothing no matter how softly i tried it kept coming off , i thought the bolt had come off completely but now that im looking at at i’m noticing the gear is extremly moveable and it has no grip on the bolt. i looked at my old bike to see what it had to stop this and it had a screw going into the pin/bolt, should i do the same with this or is there another fix? i need to know if this is a normal thing or if this bike was put together badly (i didn’t build it)
i’ve only ridden the bike 3 times and have had no falls or accidents with it.

Loosen the pinch bolt and then tighten you crank down it looks like the only thing to actually hold it in place is your crank pressure
Losen the pinch bolt on the crank arm then tighten the bolt that goes throught the crank arm until there is no more movement. Tighten pinch bolt.
Then go around the bike and nip every nut and bolt up just in case
The chainring butts up directly against the crank arm, its shouldn’t have spacers between the arm and sprocket, its why the sprocket bar isn’t sitting deep enough to hold the sprocket. Those spacers if required go on the inside of the sprocket against the bb bearing.
it’s unfixable dude
