ClamAV not running after excluded dirs

Hi guys,

Don't know why my clamav not running, has a red dot status, after I entered an excluded dir.
It working fine if I removed the excluded dir.

I tried with/without " ", but error persist.
Here's my parameter:

--exclude-dir=/media/54bf67db-da31-4c50-bb3c-27140944b223/Personal/OC_Apps/apps/files_external/3rdparty

I look at the links above, but don't see the solution.
What's the correct syntax?

It's working, thanks.
