Unable to Unzip - Gradle-Launcher-4.0.1.jar

Hi,

I am making a game for Android and have both Google FireBase and Google play plugins installed.

Opening the project gives me this error. The file in question does exist in the file location and is not set to read only.

Spoiler: Error Opening Zip

Trying to build the project gives me this error. I believe these errors are related to one another.

I've checked the location it specifies in the file path (C:\Program Files\Java\jdk1.8.0_121\bin) and there isn't the GradleLauncher.jar set. I haven't removed said file and this error has only recently started appearing.

My Android SDKs are attached.
Unitys paths to the JDK and SDKs are valid and I am doing a Gradle Build
