My Google Play Store is glitching so I can't download Minecraft

I already had this kind of problem, and I had to clear the cache of Google play store.

The TLDR: Go into the Google App Store App settings (the app itself, not minecraft's) and Clear Cache and Data.

You will have to sign back into the gmail account related with your games.

If that doesn't work, I would say go get the APK on a site and install it manually. Its less secure but it will bypass any problems the App Store may be stuck with.

Sometimes this can happen if your device isn't compatible with the game. Check to see if your device is up to date. If it is, this could be a bug that is an issue you might want to take up with google playstores.
