For SQL Data Profiler, the queries require access to the system views INFORMATION_SCHEMA.COLUMNS and INFORMATION_SCHEMA.TABLES. For every database that a connected account wants to profile, the account needs permissions granted to access these system views. By default, sysadmin has these permissions.

Please also refer to the Microsoft document "GRANT Server Permissions (Transact-SQL)".
You can now download SQL Data Profiler v126.96.36.1990 which checks upon startup whether the proper permissions have been set.
