The remote is crashing on 2 Android 10 devices that I own. The remote worked well before the upgrade to version 2.3 was applied two my two android devices.
Report this directly to Roku:
chat or email: https://support.roku.com/contactus/contact-options (choose setup/<model>/other/need more help?)
Also, if you havent restarted your Android 10 devices since installing/updating the app, do so and see if it makes any difference.
Otherwise, rollback the Roku app to a previous version (uninstall the app, install older version, disable auto-update for the app in the play store)
I forgot to mention that I did reboot both devices, still not working correctly. Thanks, for the contact link.
