Please describe the issue here:

Trying to take build for our app in 32 bit as well as 64 bit architecture. Its showing an error like the one given below, when I try to do any firebase auth tasks such as signing in a user via email and password. In the earlier firebase sdk version we are getting the error in the link (https://github.com/firebase/quickstart-unity/issues/466) for the 64 bit architecture. where as the 32 bit architecture was working fine. After adding the latest firebase sdk 6.5.0 we are not getting it working correctly even for the 32 bit architecture. (Please list the full steps to reproduce the issue. Include device logs, Unity logs, and stack traces if available.) Download the quick start unity project. Add latest firebase sdk 6.5.0 and do a force resolve using the google play resolver and take the build by enabling both 32 bit and 64 bit architecture. You will get an error like this:
