My lightroom keeps glitching or not listening to my requests

My lightroom isn’t responding when I want to move or delete a remove section. It keeps freezing. When I want to change the opacity, it has no problem doing that, but pauses or lags at other tasks. It has been doing that in the edit section too. For example, just clicking on the edit section to change from the remove tool will take a while. Has anyone else experienced this or know what to do?
