Opening Realm files of format version 5 is not supported by this version of Realm

I can't find a way to read my Realm file. I assumed Realm is backwards compatible. The Realm objects/attributes/classes have remained exactly the same. I tried changing the schema and also tried custom migration, which is impossible because I get "Opening Realm files of format version 5 is not supported by this version of Realm" as soon as I tried to read from Realm. I have tried many tricks i've read in other posts such as forcing readOnly to false:

    let version = Realm.Configuration.defaultConfiguration.schemaVersion
    print("schema version \(version)")
    var configuration = Realm.Configuration(readOnly: false, schemaVersion: 1)
    try! Realm(configuration: configuration)   //FAILS Opening Realm files of format version 5 is not supported by this version of Realm
    configuration = Realm.Configuration(readOnly: true)
    let realm = try! Realm(configuration: configuration)

I can't update the app on the App Store because people with a previous version will have their app crash, and I don't want to delete their Realm file and get bad reviews because they lost all their data. Is there any option without downgrading to an earlier version of realm?

I'm using XCode 12.4 and swift 5. The schema of the Realm file is unchanged. The issue was supposed to be solved in Realm v5.4.1 on 9/20/2021. I have the latest version of Realm installed but the issue is not resolved. https://swift.libhunt.com/realm-cocoa-changelog?page=4
I've have also tried resetting the integration state:

pod cache clean Realm
pod cache clean RealmSwift
pod deintegrate || rm -rf Pods
pod install --verbose
rm -rf ~/Library/Developer/Xcode/DerivedData

The core confusion is in the wording Realm files of format version 5.

The file format version is a different number from the Realm SDK Version.

Unfortunately, I don't think this correspondence of versions is clearly documented anywhere.

Searching the changelog for mention of format is the only way I know.

An important version probably fixed your upgrade woes 10.7.1 which Restores support for upgrading files from file format 5 (Realm Cocoa 1.x)

From my sheet which has much more detail:

  • SDK 10.8.0 Generates Realms with format v22
  • SDK 10.0.0 Generates Realms with format v11
  • SDK 5.4.0 Generates Realms with format v11 also (last of the pre-MongoDB standalone?)
  • SDK 2.4 ... 2.10 format 6
  • SDK 1.x format 5

Question was answered on Github:

v5.0.0 dropped support for opening Realm files written by versions before v3.0.0.

We support migrating from 6+ and the 5->6 migration just consisted of recreating the string indexes.
