The trackpad click is unresponsive after screen unlock on MacOS Catalina on MacBook Pro 2018 I upgraded my MacOS from High Sierra to Catalina and now I find that after screen unlock, the trackpad click becomes unresponsive. I have to go to desktop (dragging three fingers up) and select a window (of any app) to make the trackpad click responsive again. I didn't have this issue on MacOS High Sierra. Please help in resolving this.
ajay. 

Do you already have the latest version (10.15.4)? If not, try to update, if yes, try the following: 

1) Reset your Mac's NVRAM or PRAM. 

2) If you continuing experiences issues, try to reset the SMC of your Mac.

I hope that works.
