Hi,
Thank you for posting the question on Microsoft community forums. It looks like you are unable to open task manager and getting an error “The application failed to initialize properly (0xc0000006) **”.**Please answer few questions to narrow down the issue.
1. Are you able to open task manager from Safe mode?
2. Which is the antivirus program installed on the computer?
3. Are you aware of making any changes to the computer prior to the issue?
Method 1: Step 1: Check if the issue persists in Safe Mode with Networking.
Safe Mode with Networking starts Windows in safe mode and includes the network drivers and services needed to access the Internet or other computers on your network.

Step 2:
If you do not face the issue in safe mode, then put your computer in clean boot and check for the issue.
Putting your system in clean boot state helps in identifying if any third party applications or startup items are causing the issue. If yes, you may have to contact the program manufacturer for any updates or uninstall and re-install the program.
Here’s the article you may refer to for steps with reference to the same.
