Bump, same problem here, I am site coll admin, and Flow enviroment admin.
As a work around I tried - different enviroments, different SHP lists, new SHP list, recreate SHP conectors for ms flow and creating flow as a different user with enviroment maker rights.
Will provide more info if need be (i.e. CTRL+ALT+A output). This is really unfortunate, as I cant do anything related to SHP.
