Old laptop runs our documented FR5 read-only identity test. Rebuilt one rejects an argument before connecting. Same script, several SDK folders, no imported-copy record. What should I compare first?
Capture the loaded module path, version evidence and method signature from each actual launch, alongside interpreter, working directory and launch method. Preserve the working setup first. A folder you remember downloading may not be the one the script imports, and this pre-connection error is no reason to change controller networking.
Different imported paths and signatures found. The rebuilt launch uses another copy. Working laptop preserved; supported-version choice and documented retest still pending.
