Error: The terraform-provider-google_v4.44.0_x5 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

[slevenick]

Can you reproduce this without a module? I'd like to test this out and see how we missed this bug in the test/release process.

[slevenick]

I'll be releasing 4.44.1 today if everything goes according to plan to fix this issue

[github-actions]

I'm going to lock this issue because it has been closed for 30 days ⏳. This helps our maintainers find and focus on the active issues.
If you have found a problem that seems similar to this, please open a new issue and complete the issue template so we can capture all the details necessary to investigate further.
