HI! Based on the information you've provided, it sounds like there may be an issue with your front derailleur or chain. If the chain is not engaging properly with the front chainring, it may be slipping and causing the crank arms to move without turning the chainring.
It's also possible that there is a problem with the bottom bracket, such as a loose or worn-out bearing. In this case, the crank arms may be moving freely without properly engaging with the chainring.
To diagnose the problem, you may need to inspect your bike more closely. Check the front derailleur to make sure it is properly aligned and adjusted. Inspect the chain to make sure it is not excessively worn or damaged. You can also check the bottom bracket to make sure there is no play or unusual movement.
If you're not comfortable performing these checks yourself, it's best to take your bike to a professional bike mechanic for a proper diagnosis and repair.
