Hello,
I turned my Mac on and now I can't play videos on iMovie, QuickTime, YouTube or Netflix. I tried updating my computer, and after restarting it, it worked. However, I turned it off and back on and it won't play again.
Has anyone been experiencing this? Does anyone know of any solution?
MacBook Pro 13″, macOS 11.2

To trouble shoot further you can:
—Try a SafeBoot https://support.apple.com/en-us/HT201262
Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc.
Login and test. Reboot as normal and test as caches get rebuilt.
In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however 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.
—Test issue in another user (or guest user) account https://support.apple.com/en-us/HT204443
This will tell you if it a universal issue or isolated to your user/admin account.
Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus

I have this same issue. Started yesterday after the 11.2.1 update. Videos won't play in browsers or on in Quicktime. Same issue is Safe Mode.
Unable to play videos - MacBook Pro (13-inch, M1, 2020)
