This ransomware is not decryptable. The options you have right now are the following:
1) Recovery: In rare cases ransomware fails to delete shadow volume copies or fails to delete the original files properly. You can try to
recover files via shadow volume copies and file recovery software. The success rate is very low, though.
2) Wait: Backup encrypted files and a ransom note and wait in case a solution comes up later. Maybe law enforcement gets hands on the keys or the criminals publish the keys as it happened with, e.g., GandCrab. I suggest reading the news on this.
3) Pay: There is the option of paying the criminals, but we highly recommend against this step. You will just fund later attacks. You may also pay without getting your files back. These are criminals and as such not trustworthy.
Please let me know if you want assistance with recovery.
