From 9to5google:
We’ve observed the problem on Spotify v8.8.60 on both Pixel Fold and Galaxy Z Fold 5. That version is currently in the beta track, and it’s not happening on a Pixel 7 we tested using v8.8.58, so most users should be safe.
Just go to the Play Store and leave the beta if it’s crashing for you.
Additionally, you would have to uninstall and reinstall the app after you’re effectively out of beta.
I don’t think that the Play Store would ever downgrade an app version, as Android doesn’t allow that.
Or wait until stable version has higher version number than beta and it should updated automatically.
