For about a week my trackpad has started having an issue, it will suddenly stop being able to "left click", so single tap. It fixes with a restart but it keeps happening multiple times per day and it's really annoying. I think it's a software issue because the two finger "right click" usually works even if the left click doesn't. Also it seems to be locking the cursor into it's last state, because a couple of times the issue happened when I was moving a window and then the window was stuck onto my cursor and I could do nothing to get it off until I restarted. Any help would be much appreciated

To trouble shoot further you can:
—A SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies
Does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, third party system modifications and system accelerations are disabled temporarily.
Login and test. Reboot as normal and test. Caches get rebuilt automatically.
This test will tell you if third party interference; most extensions etc are not loaded in safe boot mode.
—Test issue in another user (or guest user) account Change Users & Groups settings on Mac - Apple Support
This will tell you if it a universal issue or isolated to your user/admin account.
***wireless keyboard with rechargeable batteries— connect the charging cable, this will make the wired keyboard successful Safe Boot your Mac.
unplug all non-essential peripherals when testing
Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus
