Spurious error messages (as if checking on a corrupted/truncated file)

[harikb]

Just installed bingo yesterday and using with vscode with the following settings. The entire settings file is given below (in case some conflicting setting exists). There is no way a line like return nil should give an error for undefined variable n. Also the second picture will show that the error message seems to skip a character from the middle of the variable name
