Context Limit Exceeded When Uploading Large File

Bug Description
when attaching a large file i get this: Error: Error during compaction: Error: API Error: 400 {"type":"error","error":{"type":"invalid_request_error","message":"input length and max_tokens exceed context limit: 198127 + 20000 > 200000, decrease input length or max_tokens
and try again"}} but after this if i want to ignore this and continue it keeps giving the same error, the only solution is to exit and run claude again.
