[Bug] Anthropic API Error: Missing Tool Result Block for File Scanning

Bug Description
I'm asking claude code to read the Ancient Art of War manual, and the dos download, and to make a plan for creating a browser version ( yes, I know this exists already, I wanted to see how the new sonnet 4.5 did with it ). After reading the pdf, this happens : ⏺ Bash(find AAoW_DOS_download/ -type f | head -20)
⎿  AAoW_DOS_download/PC
AAoW_DOS_download/PD
AAoW_DOS_download/PM
… +17 lines (ctrl+o to expand)
⎿  API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"messages.2: tool_use ids were found without tool_result
blocks immediately after: toolu_01GXrYuTchWMMFnit4RAs1kR, toolu_01Xnwzn75jDGRq32DeWhNgWz. Each tool_use block must have a corresponding
tool_result block in the next message."},"request_id":"req_011CTexH8Rhz8ovVfm8j1B3q"} : and it happens repeatedly. I've tried changing the folder name of the download folder to no avail. claude code has read all of these files in an earlier session with no issue, but now I'm stuck on this error every time.
