Few of the workaround you can follow to achieve the above requirement;

  • Make sure that you have following permission to that subscription Owner or, User Access Administrator( must have a role that includes Microsoft.Authorization/roleAssignments/write permissions) to assign or remove.

  • If you have above permission Check the role which have defined in storage account same as what you have mentioned want to remove. Or it exist or not.

  • And make sure that the role which you want to remove, that not showing as inherited If so you can not remove those assignments as you are trying to remove a role assignment at a child scope.
