Terminal app crashing forever never start again

Try booting into Safe Mode to see if you still have the crashes. If this works, then most likely you have some third party software which is causing the problem.

Try creating a new macOS user account. Log out of your current macOS user account, and log into the new macOS user account. Do you have the same issues with Terminal? If not, then the issue is isolated to your main user account (either a login item, or a configuration issue, or corrupt preference file).

You can run EtreCheck and post the report here so we can examine it for clues.

What are you doing in the Terminal when these crashes occur? If you are not using the Terminal app, then what app may be triggering the use of the Terminal?

Edit: Have you tried a simple reboot?

A properly-working MacBook Pro running an appropriate version of MacOS does not panic in this way (segmentation fault is a reference to memory not owned by the currently running task). There is nothing in Bare Terminal that causes such panics.

However, there are many, many things you could have added to your Mac that could cause this symptom, (not even counting RAM memory errors, but their symptoms tend to be wildly variable from run-to-run).

I recommend you download an run this little Discovery program, Etrecheck. it fixes NOTHING. Its sole reason to exist Is the deep frustration felt by its Developer, a frequent senior contributor here, at not having easy access to human-readable information from the INSIDE of your Mac.
