How can i reverse my android studio to escape this PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException:..?

I recently updated my flutter version to 2.0.0 and it worked fine on iOS after updating the pub packages versions to the latest. It unfortunately didn't work on Android and i thought of updating the Android studio. Since then I have been getting certificate errors and I have tried the following, specified in other stackoverflow answers with no result:

1. adding certificates from maven,jcenter and google to jdk
2. changed build.gradle version several times
3. downloaded new sdk tools
4. accepted all licenses from flutter doctor --android-licenses
5. tried reinstalling an old flutter and running an app from it
6. downloaded new jdks

.. all to no avail At this point, I just want my old android back :(
