My Macbook Pro 2018 keyboard backlight stopped working. However, it still lights up on the login screen. Once I'm logged in, Touch Bar buttons don't respond, and neither does the manual option on Control Centre. I have tried both usually suggested resets but nothing happened. Can anyone help?
MacBook Pro 15″, macOS 13.2

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.
—A 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; most* extensions etc are not loaded in safe boot mode.
Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus
all known to cause issues on the macOS
