This issue is on our radar, I do apologize for it.
For what it’s worth, version 1.38.1 (645) is a beta release, so it’s not a full public release yet. If you want to stop beta testing, you can opt out at https://play.google.com/apps/testing/org.inaturalist.android Then download the latest public release if you want. You can always opt in to beta testing later using the same link.
