Just to expand on what @JackGruber has said...
I have been trying to keep a record of when internal profile versions have been updated for support questions such as this.
When you upgrade to a newer version of Joplin if it uses a newer internal profile version you cannot later downgrade back to a version that uses a lower internal profile version.
In your case your data is using internal profile version 47 so the earliest version you can install without having to re-download your data (assuming you sync your client to online storage) is version 3.0.3.
