Answer
As per this comment, you need to install a newer NDK from the canary channel:
Android Studio menu,”settings > Appearance & Behavior > system Settings > Updates”
choose “Canary Channel”
The canary NDKs will be enabled for download:
“Tools > Sdk Manager > SDK Tools”
( assuming “Show Package Details” is enabled ) “NDK side by side”
Or you can install it from the command line with
sdkmanager --channel=3 --install 'ndk;21.1.6363665'
