I tried looking at prior solutions and implementing them, but they didn't work. I also tried adding android.useAndroidX=true android.enableJetifier=false to my gradle.properties but the code was still giving this error. Any help would be very appreciated.

As per what Gabriele said, migrating to androidx fixed the problems
