Player can't jump, even if grounded

Unity Engine
1

I’m using a script given to me for a uni project (never used unity before) and it allows me to jump, move etc.
It worked great to begin with but seemingly out of no where i couldn’t jump anymore. I have no idea what i may have changed but i’m almost certain its nothing to do with the script because I’ve never edited it.

The player is still grounded as you can see in the image but jumping doesn’t work (i can still move sideways)

I also have another issue right now where if i zoom in everything disappears, i don’t think the issues are related as i’m pretty sure i got it after the jumping one. I tried going into 3D view to see where my scene camera was and i can find the level, it looks like i’m either extremely far from it in 3D view or its super small

Found the issue with the jumping, for some reason whoever coded this decided that no one would ever want to have a character only jump once and so it only works with multi jumps smh.

Though my tiles are still disappearing when i zoom in

So i found the issue with my tiles disappearing, my scene camera position is about -57,000 on the z plane, i created a new sprite to find it automatically placed its self that far back, i have no idea how to move the scene camera

Just set all the Z coordinates to 0 for all sprites and tilemaps and use the Sprite Order stuff. Camera should be at z=-10 for default afaik, so you should be able to see everything.
