RealmException: Realm at path '/path/to/default.realm' already opened with different sync configurations. Error code: 2013

What happened?

I'm facing an issue when using Realm with flexible sync and disconnected sync configurations. I initialize the flexibleSync on the main thread and disconnectedSync on a background thread (using the workmanager package), and I encounter the following error:

RealmException: Realm at path '/path/to/default.realm' already opened with different sync configurations. Error code: 2013

Repro steps

Main Thread (Flexible Sync Initialization):
final config = Configuration.flexibleSync(
loggedInUser,
[
Model.schema,
],
path: Configuration.defaultRealmPath,
syncErrorHandler: (SyncError error) {
debugPrint("Error message: ${error.message}");
},
);

Realm realm = Realm(config);

On WorkManager Callback Function (Disconnected Sync Initialization):
final config = Configuration.disconnectedSync(
[
Model.schema,
],
path: Configuration.defaultRealmPath,
syncErrorHandler: (SyncError error) {
debugPrint("Error message: ${error.message}");
},
);

Realm realm = Realm(config);

Problem
The workmanager callback is called whenever I submit my form, and I get the error mentioned above: RealmException: Realm at path '/path/to/default.realm' already opened with different sync configurations. Error code: 2013.
