Trackpad suddenly not clicking

Hi, so I’ve had this laptop for over a decade and I’m determined to keep using it until it literally explodes, so a few weeks ago I got a replacement battery from here & installed it. It’s been great & I haven’t had any issues, but today I went to use it as usual and suddenly my trackpad wasn’t clicking. I could double tap & move the mouse but the actual click sensation is gone. I spent an hour troubleshooting, restarting the computer & reinstalling the battery but the problem persists & diagnostics turns up nothing. Any suggestions would be appreciated, thanks!
