Report Fixed asset roll forward - error during the 'Format mapping' run


I'm trying to run report Fixed asset roll forward, but I get an error "Error occurred during the 'Format mapping' run. Object reference not set to an instance of an object.". Configuration for ER is installed. Debugging is complicated as class throwing error is not accessible - ERFormatMappingRunUnattended. Could you, please, advice what can cause such error or how it can be identified? D365 v10.0.8

Thank you.
