Consequences of not coming to saudi on work visa

Hello. I am new to this forum. Can someone plz guide if I apply for MOH job in my home country and get a saudi  work visa (moh) and later develop second thoughts of movin going there once visa is issued what would be the consequences in the future  if I want to work in saudi.
Thanks.

Is the work visa issed on your passport already? You just have to fly to KSA?

I believe there is no consequences...

My prblm.is about my visa stamping is delying , reason, agent told position canceled ?? what is reason?? Its affctz my visa aslo??? How much validity of saudi ?

If its canceled you must find another employer or the visa has expired or somebody has taken in your place
