I have just created a synapse analytics workspace, on opening it I get an error message similar to the below.

From my research, I have gr anted storage blob contributor role to the synapse application as well as the user assigned managed identity.

Going into Manage >> Access Control, I cannot seem to assign roles.

I expect a screen with all the assignment roles, but I get the below

Is there a way to view the actual error message to see what is causing the problem ?
