I followed these steps: 1. I exported db with Settings//Import/Export//Database export//PodciniBackup-2025-01-13.realm 2. I installed the latest version of Realm Studio (Version 20.0.0). 3. I opened Realm Studio and selected Open Realm file. 4. I got the error: `LockFileEx() failed: Incorrect function.` I'm a python dev and not familiar with Android dev. I really miss the SQLite because there is no real python support of Realm. I open this bug because I didn't found anyone that met this issue. Your app is great, anyway! ### Expected behaviour _No response_ ### Current behaviour _No response_ ### Logs _No response_
