Keystore recovery

Hello there,
so i have a very big problem. I overwrited my keystore by fault. But i very beginner in kodular and in apps in general. So i have my old apk’s but i dont have any idea how to find my keystore from them.

P.S i dont have any idea about code or programming, so i want if anyone can help me with easy steps how to find it, what programs can i use etc.

Thanks a lot

Unfortunately, the only option to restore is from a backup

Not even if there is a way to decompile the apk?

As I said, unfortunately none. You can always create a new keystore

I have a problem with play protect. i get a warning all the time and with my old keystore i didnt had this problem. Any idea to get rid of it?
