Observed behavior and steps to reproduce

We randomly (random as in "we do not know how this can happen yet") the following error when calling TileStore.default.loadTileRegion

Failed to resolve tileset descriptors: database is locked

Here are the parameters we are passing:

tileStore.setOptionForKey(TileStoreOptions.diskQuota, value: 1)
        tileStore.setOptionForKey("tile-region-max-tile-count", domain: TileDataDomain.maps, value: IOSMapboxConstants.maxTileCount)

        let tilesetDescriptors: [TilesetDescriptor] = styleUrls.compactMap { styleUrl in
            guard let styleUrl = StyleURI(rawValue: styleUrl) else { return nil }

            return offlineManager.createTilesetDescriptor(
                for: TilesetDescriptorOptions(
                    styleURI: styleUrl,
                    zoomRange: UInt8(Constants.Companion().offlineMapMinZoomLevel)...UInt8(Constants.Companion().offlineMapMaxZoomLevel)
                )
            )
        }

        let tileRegionLoadOptions = TileRegionLoadOptions(
            geometry: metadata.boundingBox.asPolygon(),
            descriptors: tilesetDescriptors,
            acceptExpired: true,
            networkRestriction: .none
        )!

tileStore.loadTileRegion(
            forId: metadata.id,
            loadOptions: tileRegionLoadOptions

We sadly do not have anymore info for now. I have added some trace logs to our released app to gather more information but any assistance on how to gather more information would be appreciated.

Even better if you are already aware of this issue

Expected behavior

Not getting any database locker error 😅

+1 for this issue. We are still encountering this issue using Mapbox 10.10.1
