What's Wrong?

On version v2.0.44 I wasn’t able to access the plugin marketplace got this error:
Manage marketplaces
│ > ● claude-plugins-official
│ anthropics/claude-plugins-official
│ • Updated 4/24/2026

So I have updated to the latest version now I can’t use Claude getting a new error:
API Error: 400 {"error":{"message":"{\"message\":\"context_management: Extra inputs are not permitted\"}. Received Model Group=aws/claude-opus-4-6\nAvailable Model Group Fallbacks=None","type":"None","param":"None","code":"400"}}
When reverting back to 2.0.44 it work but no marketplace can you please help?

What Should Happen?
