Expected Behavior

No error; and maybe also not reference the terraform registry?

Actual Behavior

> tofu providers schema -json
╷
│ Error: Failed to load plugin schemas
│ 
│ Error while loading schemas for plugin components: Failed to obtain
│ provider schema: Could not load the schema for provider
│ registry.terraform.io/hashicorp/azurerm: failed to instantiate provider

Steps to Reproduce

1. tofu init
2. tofu providers schema -json

Additional Context

This does not error when using a different architecture, darwin_arm.

Actually. Tried on another box and it worked. I think this might be a memory limit issue. or more likely OS issue - failing runs are using Alpine OS. The generated json is 2.9M.

Updated with more context that it might be a memory issue (doubtful) or maybe an Alpine Linux OS issue.
