The app crashes when updating from an older version

In v0.98.3, building with Xcode15 did not crash on iOS17 but crashed on older versions like iOS14.

So I tried updating existing apps from v0.98.3 to v10.43.1.
There were no issues with new installs, but updating from v0.98.3 resulted in the following error:

Terminating app due to uncaught exception 'RLMException', reason: 'Database has an unsupported version (3) and cannot be upgraded'

Does this mean v0.98.3 already does not support DB upgrades?
If so, which Realm version would allow DB upgrades?
