Couldn't find a valid ICU package installed on the system

Currently I'm forced to upgrade Roon from 1.7 to 1.8 to be able to connect with any app. If I click upgrade and then relaunch the process exits with the following message:

Process terminated. Couldn't find a valid ICU package installed on the system. Set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support.

looks like adding the following env will work around the problem:

DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1

I suggest you install icu. That env car could lead to inconsistencies.
