Audacity 2.3.0 buzzing and playing quickly

I guess I’ve been spoiled. I’ve used Audacity for years and never thought twice about it.

I updated to 2.3.0 and when I attempted to play an .mp3 file I get a weird LOUD buzzing noise and superfast talking. I can’t begin to understand any of it. I’ve installed/uninistalled/reinstalled with/without default settings and it doesn’t help.
the file plays perfectly on Windows Media Player.

I accidentally toggled Quick Play and it looks like it’s running 6x normal speed. I toggled it off and that doesn’t help.

Has anyone else experienced this?
I’m using a Windows 10 64-bit system, and my M/B is 8 years old but has been so reliable I’m happy with it and my SSD drives.

I’m under pressure to fix this and am running out of ideas…

Help Please!
