TV app keeps crashing in few minutes

Try these generic Mac troubleshooting procedures:

• How to use safe mode on your Mac - Apple Support. ‘Safe mode’ can help you to determine whether an issue is caused by (third party) software that loads as your Mac starts up.
• How to test an issue in another user account on your Mac - Apple Support. If an issue stops happening when you log out of your macOS user account and log in with another, the issue could be related to the files or settings in your user account.

Let us know the results of these tests, to determine next steps, if needed.
