"Remove-RoleAssignmentFromUsers" throws error System.ArgumentNullException: Value cannot be null. Parameter name: path1

I run this command:
Remove-RoleAssignmentFromUsers -roleName "System Administrator" -usersFilePath C:\temp\230404David.csv -processAllEnvironments $true -outputLogsDirectory C:\temp\DavidRemovedRoles

However, there is no successful role removement.
The error is:
Exception while retrieving users with role name System Administrator from environment https://zfsalescoretest.crm.dynamics.com :
System.ArgumentNullException: Value cannot be null.
