Can you reproduce the bug?

Yes, sometimes

Reproduction Steps

use the RealmConfiguration Builder with an encryptionKey then it will crash in Radom transactions using mostly copyToRealmOrUpdate

realmConfiguration = RealmConfiguration.Builder().encryptionKey(key)
        .name("nameDB")
        .allowWritesOnUiThread(true)
        .modules(RealmModule())
        .deleteRealmIfMigrationNeeded()
        .schemaVersion(1).build()
    Realm.setDefaultConfiguration(realmConfiguration)

example transactions

  Realm.getInstance(realmConfiguration)?.let {
            it.beginTransaction()
            val results = it.where(className::class.java)
                .isNotNull(name).findAll()
            results.load()
            results.deleteAllFromRealm()
            it.copyToRealmOrUpdate(list)
            it.commitTransaction()
            it.close()
        }

@yul13th do you have access to the affected Realm db file? We have found a potential issue when working with encrypted realms that can end up with a corrupt the database.

realm/realm-core#5174

[paolo-ermit]

I've the same problem. But opening the file after a crash with Realm studio the file is readable, it doesn't seem to be corrupted. Problem is happening with version 10.10.1 and not with versione 10.9.1

[sideprojecteu]

I also have the same problem with encrypted realm after updating to 10.10.1. It was fine in 10.9.0 and previous versions. I do not have access to db file.

realm/realm-core#5174

I can't access the file... when the app crashes the device will ask to clean cache and then the app will work for a litlle while then it will happen again and the cycles repeat. So yes, I think it is possible that the file is getting corrupted.

[finnschiermer]

@clementetb as this is a newcomer happening only after a recent release (if I read it correctly), it is likely not related to the problem in https://github.com/realm/realm-core/issues/5174

[clementetb]

@finnschiermer I see, it must be unrelated as it is an issue present since the first implementation.

@paolo-ermit @sideprojecteu @yul13th we could not replicate the issue with the information provided. Are you able to reproduce it constantly? Is it affecting an unique device? Could you write and share an example project that reproduces the issue?

[mattylase]

Wanted to add my voice to the chorus here. We somewhat recently upgraded to Realm 10.11.0. We didn't see any problems locally or in Crashlytics, but found a huge amount of problems are coming through the Play Console's reporting feature.

The only logs I have access to are from a non-technical coworker who happened to see the issue on their device. I'm not 100% sure it's related to encryption, but we are using encrypted Realm. I can't provide any repro steps or examples, as all reports are from the field of our app crash looping.
