Keycloak embedded


I started the embedded keycloak server (11.0.2) from bealdung website. I have a problem. In the upper right corner I click manage account (no difference whether from admin or user account) and i want to make any change to the account, every time after clicking cancel or save button i get 403 response code An internal server error has occured. My client has a manage-account role. I will add that i have already tested several version of the embedded keycloak server and the same thing each time. Only the standalone keycloak version work properly. Do you know what could be the reason of this ?
