Steam proton log

Microsoft Flight Simulator 2020 present some problems on launching.
Workarounding #49739 by copying netutils.dll and srvcli.dll from Windows 10,
the program is able to create a black screen and crashes right after that.
Discussing this in a specific proton Github issue (
https://github.com/ValveSoftware/Proton/issues/4134 ) that appear to occur due
to missing UWP APIs inplementation: SpeechSynthesizer and Package. According
Proton logs:
