Answer 1

I had this exact same problem and navigated to your question in an attempt to find the answer.

You are indeed right that you need to delete ~/.AndroidStudoio3.1/config/studio64.vmoptions. Android Studio stores a config to your user profile which is why the problem persisted after you uninstalled the program file itself. You can find the file you're looking for under C:\Users\YourUserName\AppData\Roaming\Google\AndroidStudio4.1. Delete studios64.vmoptions and you should be able to launch Android Studio. If you're still trying to optimize your workspace you could try:

-Xms1024m
-Xmx4096m
-XX:MaxPermSize=1024m
-XX:ReservedCodeCacheSize=256m
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-Djna.nosys=true
-Djna.boot.library.path=

-Djna.debug_load=true
-Djna.debug_load.jna=true
-Djsse.enableSNIExtension=false
-XX:+UseCodeCacheFlushing
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-Didea.platform.prefix=AndroidStudio
-Didea.paths.selector=AndroidStudio
