please help with decrypting files that are encrypted with cool encryption

First, try the EmsiSoft decryptor, if it fails to decrypt encrypted files, then use ShadowExplorer and PhotoRec ( https://www.myantispyware.com/2019/12/04/how-to-recover-encrypted-files-ransomware-file-recovery/ ). If these free tools did not help to recover encrypted files, then you just have to wait for the moment when decryption becomes possible. Follow the news on our website.
