Hai Musab,

Thanks for your reply. Solution proposed in the KB Article is to Activate/Deactivate the flow designer but I'm not even able to open the flow designer.

I am also getting the same issues with my subflow post promotion. I am using Quebec version. 

I edited the subflow and republish and I even duplicated the subflow but no luck still the same error.
