You can try both—

resetting the System Management Controller Reset the SMC of your Mac - Apple Support

resetting NVRAM/PRAM Reset NVRAM on your Mac - Apple Support

no resolve—

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.
