Error Playing DASH Content

I have a problem playing encrypted .mpd content using AVPlay on 2020 TV. The log keeps returning PLAYER_ERROR_NOT_SUPPORTED_FORMAT. I used Verimatrix DRM at first. I thought it was a compatibility issue so I tried using other DRM but returned with same error. Playing unencrypted content, however, was succesful. Does anyone have ideas what could be causing this error? Please help
