Little extra context here I just replaced the bottom bracket and crank arms. It’s a sealed cartridge BB, square tape, and the same size as the old one. Cranks are brand new too.

Looks like the crank/chain ring interface is slipping and I don’t think it’s related to your new bottom bracket.
It might be a lower quality crank with separate crank and spider that are swaged together, but have come a bit loose.
If so, I don’t think it can be fixed.
