The Android Emulator team has pushed 30.1.5 which fixes this issue in stable. The dev build, 30.2.0 does not contain this fix. It should be available "soon" according to the Googler's working on this.

Another note, if you experience poor performance in your emulator you may wish to try using the host's GPU for rendering. This can be accomplished by running the following command in your terminal where -avd is the name of your emulator device with spaces turned to underscores.

~/Library/Android/sdk/emulator/emulator -gpu host -feature HVF -avd pixel_3a_api_29

Old information, kept for educational value:

This is the reference to the commit fixing this issue for Big Sur. This looks like it should be released in the emulator 30.1.5 (see log https://android.googlesource.com/platform/external/qemu/+log/refs/heads/emu-30-release) which should be in the next canary build.

If you can't wait, you should be able to build off that branch. Lightly tested guide heavily pulling from the readme of the repo:

# Get the google repo tool - you can skip if you already have it
curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > /usr/local/bin/repo && chmod +x /usr/local/bin/repo

# Get the code, will take some time. Probably best to go get a coffee here or run on a server if you have poor internet
mkdir -p $HOME/emu-master-dev && cd $HOME/emu-master-dev
repo init -u https://android.googlesource.com/platform/manifest -b emu-master-dev
repo sync -j8

# Get XCode 10.1 - required
https://download.developer.apple.com/Developer_Tools/Xcode_10.1/Xcode_10.1.xip
sudo xcodebuild -license accept &&
sudo xcode-select --install

# Get MacOS 10.13 SDK which is required
export XCODE_PATH=$(xcode-select -print-path 2>/dev/null)
git clone https://github.com/phracker/MacOSX-SDKs
cp -r MacOSX-SDKs/MacOSX10.13.sdk/ "$XCODE_PATH/Platforms/MacOSX.platform/Developer/SDKs"

# Build the emulator, which will be another coffee break...
cd external/qemu && android/rebuild.sh

# run it :)
./objs/emulator -list-avds
