Hi,

Since I started experiencing issues on my 2017 16" MacBook Pro, the touchbar keeps flashing, as shown in the atatched video.

For Touchbar issues on an Intel Mac— the best you can do is

—Try resetting the SMC https://support.apple.com/en-us/HT201295

Even though SMC controls the touchbar, some USB is in play, so this would be NVRAM (or reboot.) notice, among others:

Touch Bar Backlight

Apple T2 Controller

Touch Bar Display

—Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379

(get at least two-three rounds of the chimes when holding the NRAM Reset)

 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 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.  Caches get rebuilt automatically.

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/guide/mac-help/set-up-other-users-on-your-mac-mtusr001/mac

  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
