Workaround - downgrade MSAL to 4.4 on the Android head but keep the iOS at 4.5. You can also keep the shared project at 4.5, it doesn't really matter.

At runtime, the Android will use MSAL 4.4 and iOS will use MSAL 4.5. This should be fine because the 4.5 release has virtually no impact on Android code paths.

I have the same issue, it seems @bgavrilMS workaround works for me for now though.

I'm having the same issue and reverting the package works.

@WilliamWatterson86 @mastermoe01 @norton287
@bgavrilMS has a fix for this. We are running a new release build now, if you would like to try it out before we officially release....here is the package:
Microsoft.Identity.Client.4.5.1.zip

[jennyf19]

Fixed in 4.5.1 release

@jennyf19 @bgavrilMS sorry for the delay getting back to you. V4.5.1 works well! Thanks for getting this out so quickly :)

[bgavrilMS]

Thanks for confirming @WilliamWatterson86 !

[mastermoe01]

@jennyf19 4.5.1 also worked for me! thank you!
