SQL Server 2019 Removing user from database results in external libraries folder error

I would like to ask what can be done in order not to receive following message that appears in SQL Server log every time a user is removed from a database on SQL Server 2019:

Couldn't remove the user (n) from database (n) from the external libraries folder, error: 0x80070003

I assume it is related to installed feature "Machine Learning Services and Language Extensions" which is installed?
