Well this may likely play a part. Which Android version is this build?
Most devices do not get Upgrade of Android version OTA
- only monthly OTA of /e/OS version happens, then on community / dev builds one has to do a manual upgrade of Android version.
For certainty please quote your full build_version_string found in
Settings > About phone > Android version > /e/OS version.

Long press on this /e/OS version to copy to clipboard

OR tap on /e/OS version then Long press on /e/OS version to copy to clipboard.
The official advice is to treat the upgrade of Android version as a fresh install, but as long as you have important things backed up you can Upgrade Android 12 (S) to Android 13 (T) without Format or wipe data as described Dirty upgrade to /e/OS-T is possible ! (But not for all devices).
