64 bit android project failing to generate apk - il2cpp backend

I am working on an IoT project at the moment. Whenever I try to build using the il2cpp backend for 64 bit apk it fails to do so even though it shows as succeeded. I have researched and tested through most existing threads about t$$anonymous$$s so I could really use some help from Unity or someone who might have faced a similar issue.

Unity version for t$$anonymous$$s project was originally 2018.2.21f1 but I have upgraded the project to various Unity versions all the way up to the most recent LTS release.

I will post more info if anyone needs it but could really use some genuine assistance here.
