Problem with APKs on custom ROMs

I recently moved to a custom ROM that doesn’t have Google services, and now some of my apps won’t open because they ask for Google Play authentication. I tried installing the APKs directly, but they still don’t work.

After looking around, I found that using modded APKs is one way to fix this. I came across gvmodapk.com, which has been helpful for me to get versions that don’t need Google login.

Has anyone else faced this issue? What solutions worked for you?
