MacBook Air 13″, macOS 11.7
Try booting into Safe Mode to see if that makes any difference. If Safe Mode works, then it may be due to some third party software that is installed.
If you have an Intel Mac, then try an SMC Reset and a PRAM Reset (hold the PRAM Reset for at least 2 chimes).
Otherwise, it is most likely a hardware issue and the laptop will need to be repaired. It may be due to a bad Trackpad, or a swelling battery which is pressing on the underside of the Trackpad.
FYI, it is always best to include the exact model of your Mac and version of macOS used whenever asking for assistance online so responses can be personalized for your system configuration. You can get this information by clicking the Apple menu and selecting "About This Mac". Or if you cannot use the Mac, then enter the system serial number here:
