In the latest level, the coins end up on the floor but I can't pick them up since the coins end up way below my physical floor.
What do I do to fix this? Can't continue the game.

Which level is this exactly? is it where you have to smash several vases?
it could be that recalibrating your floor level resolves this issue

Not related to the coin ewata is talking, but the very last coin is not easy to take because I had to go outside my safe border. I had to partially remove the mask to be sure I didn't tap a wall or something.

Same, ended up reloading after switching from stationary boundary to room-scale on my Qwest2 and stretching really far to grab them.
