Uninstalling SQL Server 2016 Standard edition error 25012

I'm trying to uninstall SQL Server 2016 (64 bits) Standard edition, but only these features:

Database Engine Services and PolyBase Query Service for External Data

I'm getting errors:

Error installing SQL PolyBase
Cannot load Counter Name data because an invalid index '' was read from the registry.
Error code: 0x80131509

and

Error installing SQL PolyBase
There was an error attempting to remove the configuration of the product which prevents any other action from occurring. The current configuration of the product is being cancelled as a result.
Error code: 25012
Log file: C:\Program Files\Microsoft SQL Server\130\Setup Bootstrap\Log\20180820_201330\sql_polybase_core_inst_Cpu64_1.log

Please could someone help me?

Thank you
