also opening a new folder opens a new tab which is annoying how do i revert it.

thank you!

EDIT: i already tried restarting my laptop

Have you tried restarting the machine and compare your results...?

Relaunch Finder...? >Force Quit>Finder>Relaunch

Uninstall any and all third party Antivirus, Cleaners, Optimizers, VPN, speeder uppers....

all known to cause issues on the macOS.

no insight—

To trouble shoot further you can:

—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. 

—SafeBoot How to use safe mode on your Mac - Apple Support will sort many anomalies

Takes a bit longer to get to the login screen, does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, font cache, etc., third party system modifications and system accelerations are disabled.

Login and test. Reboot as normal and test. Caches get rebuilt automatically.

a reboot will put it back to normal mode.

This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.
