H1B Transfer with EmployerB denied; Previous employer (EmployerA) haven't revoked H1B

[kumars1999]

I was with Employer A until July 1st 2018. Employer B applied for H1B Transfer and I started working for Employer B after receiving the Receipt Notice on July 1st 2018. H1B Transfer got denied yesterday. My previous employer (Employer A) didn't revoke my H1B. I still have a valid I94 and Visa Stamping.
Can you please provide me the options that I have now to continue working?
Can I go back to Employer A since he didn't revoke my H1B?
