Error after migrating to Android.X

Question

Hi,

I have migrated my app to Android.X and started getting below error when trying to Release my app but I have no issue when running it on Debug mode.

Hello,​

Welcome to our Microsoft Q&A platform!

What your linker settings? Please change it to None, then release it, if you will get the same exception.

Then please share Android option screenshot that contains all the settings when release.

Best Regards,

Leon Lu
