Hi rheamae139,
Please try clearing cache and data of Google Play Store and Google Play Services.
(Settings > Apps & notifications > Google Play Store/Google Play Services > Storage > Clear Cache/Data)
Please also try resetting app preferences. (Settings > Apps & notifications > See all apps > three dots on the top right > Reset app preferences)
We would suggest you also check the troubleshooting steps provided by Google:

If the above does not improve the problem, please tell me which apps have this problem, whether it is happening under WiFi or 4G, and what are the versions of Google Play Store and Google Play Services.
Thank you
🙂
