I had this issue due to having the Reporting Services databases in an Availability Group. When we failed over (for the first time) there were a bunch of permissions not correctly set, specifically the RSExecRole was not there. The reports worked, but not the subscriptions and we couldn’t edit any of the report settings. Upon saving the subscription you see the error on the screenshot above.
