IDEA Ultimate 2018.2 - Unable to save settings - Unable to create file / Windows 10

This problem started appearing randomly after updating to 2018.2. It is really annoying as I cannot create new classes, a lot of errors are appearing. Gradle is also reporting "Access denied" when trying to build the project.

Mind, the drive is an encrypted volume by VeraCrypt (which is mounted and decrypted everytime I start my PC), which in itself should not be a problem. I tried performing "Invalidate caches / Restart". run IDEA as an Administrator, deleting .IntellijIDEA2018.2 folder, re-importing the project. Nothing helps and the problem persists across restarts.

One pattern I noticed is that the Android Studio plugin may be the culprit, because as long as I do not open an Android project during the Windows 10 session, everything is fine. Would it be possible that the plugin is messing up IDEA's permissions? The plugin seems to be up to date.

Thank you very much for your help.

The Windows 10 Pro version is 1803, build 17134.165.
