[Bug] Anthropic API Error: Assistant message must start with thinking block

Bug Description
when using the command /context shows this message:

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason:
Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"messages.97.content.0.type: Expected thinking or redacted_thinking, but f✶uMustering…se. When thinking is enabled, a final assistant message must start with a thinking block (preceeding the lastmost set of tool_use and tool_result blocks). We recommend you include thinking blocks from previous turns. To avoid this requirement, disable thinking`.
