Tier 2- Cooling off period/BRP not collected. Advise needed

[gdfaisal]

Dear Advisors,

I had interviewed for a job and got selected in Hospital X. They issued COS (Tier 2 General) and I applied for the visa and got the visa vignette for one month on my passport. I had to collect my BRP by Nov, 2018. But Hospital X couldnt sponsor my registration with the GMC. Hence I couldn,t work there as a doctor. So I never travelled to the UK and BRP was not collected. I had informed the employer to cancel the COS they said it will get cancelled in three months.

Now I have another employer who has issued me Visa COS(Tier 2 General). They have also sponsored my GMC registration. Now will there be any problem while I apply for the visa? With problem I mean, cooling off period.?
Do I apply this like a new visa?
Anything I should be aware of while application?
