Fabric error: QuartzCore (CA::Layer::set_bounds(CA::Rect const&, bool))

Question

In my project I'm getting a lot of crashes for

QuartzCore CA::Layer::set_bounds(CA::Rect const&, bool)

From Fabric I get the following message.

Heads Up! CALayerInvalidGeometry; CALayer bounds contains NaN: [...] Details: This crash is likely due to a division by zero when applying a transform to a view or layer. Setting the 'CG_NUMERICS_SHOW_BACKTRACE' environment variable in Xcode can help pinpoint the root cause. Check out the references below for more details. External resources: Crash occurring because “CALayer bounds contains NaN: [nan 0; nan 15.1] 'CALayerInvalidGeometry', reason: 'CALayer bounds contains NaN' exception Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [nan nan]' #15

How can I solve this crash problem?

Below I share the screenshot of the crash I got from Fabric.

Below I share the class of the UserDefaults-AppLocale.swift in my project.

extension UserDefaults {
    private enum Key : String {
        case languageCode = "LanguageCode"
        case regionCode = "RegionCode"
    }

    static var languageCode: String? {
        get {
            let defs = UserDefaults.standard
            return defs.string(forKey: Key.languageCode.rawValue)
        }
        set(value) {
            let defs = UserDefaults.standard
            if let value = value {
                defs.set(value, forKey: Key.languageCode.rawValue)
                return
            }
            defs.removeObject(forKey: Key.languageCode.rawValue) // Line 29
        }
    }

    static var regionCode: String? {
        get {
            let defs = UserDefaults.standard
            return defs.string(forKey: Key.regionCode.rawValue)
        }
        set(value) {
            let defs = UserDefaults.standard
            if let value = value {
                defs.set(value, forKey: Key.regionCode.rawValue)
                return
            }
            defs.removeObject(forKey: Key.regionCode.rawValue)
        }
    }
}

It's line 29 on this Fabric.

defs.removeObject(forKey: Key.languageCode.rawValue)
