Cannot open MP3 files after Win 10 update 1809 Build 17763.529

I cannot open MP3 files after updating Windows 10 to version 1809 Build 17763.529. Is anyone else having this problem? Any options (other than changing compatibility)? Previously saved projects open.

Problem occurs with Audacity 2.3.2 on HP desktop running Win 10 Pro. I was using it and stopped to install the update. After reboot Audacity wouldn’t open MP3 audio files either by using the Audacity File>Open or by rightclicking on the MP3 and selecting “Open with>”.

I have attached a screenshot of problem.
