This question has been asked before, but I haven't seen anyone talking about it in context of the collaborate feature in Unity.
Long story short, my partner (who doesn't have the keystore on his computer) pushed an update, and I restored my Unity version to it like an idiot. This wiped my Unity folder and replaced it with what he had. I lost the keystore this way.
Previously, I had also pushed an update to Unity when I did have the keystore in the root folder of the Unity folder. My first instinct was to search through that version, but alas, it's not there. I don't know why, I'd assume Unity uploads your entire root folder when you push the project.
I do have the password to both my keystore and the signature used to push the app to Google Play. I can't just create a new keystore with the same name and password, as other users here have pointed out. I do have APKs of the game before the keystore was wiped, but I doubt it'll help. I do have Google Play App Signing enabled on the Playstore, but I can't find a way for it to help me out.
I used a data recovery software (EaseUS) to see if it could recover my keystore. It could not.
Can anyone give me hope? Thanks in advance.
If you are using Windows and if you are lucky you may have the previous versions feature enabled, right click on your folder, select propierties and there should be a previous versions tab, select it and if it is enabled there should be several dates showing changes
