Error: The terraform-provider-talos_v0.7.0 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.

probably relevant is that my cluster secrets file's aescbc_encryption_secret is null. i don't know why that is, that file was generated by the talos provider, albeit an older version

regarding the null value for aescbc_encryption_secret, can i update it with a new value? if not, what should i do?
