How to downgrade or uninstall the Android Emulator

I clicked on an update to Android Studio Arctic Fox 2020 Patch 3 and then my emulator won’t run. It gets a symbol not found error.
From what I can tell on searching this issue, it seems I may need to go back to the “older” version of the Android Emulator I was running. Or even just uninstall the whole Android Studio upgrade.
I cannot find a web page with all the versions of the Android Emulator so I can choose which one to install. Right now the SDK Tools shows I am running Android Emulator 30.9.5
Any help is appreciated. This has really stopped my progress through the book.
