This is a way for you to try and brute force your Keystore file with Hashcat. Please note that Cliff on Crypto does not support hacking!
Command-line: hashcat64.exe -m 15700 --force -D1 hashcode.txt password.txt -w3 -r rules\dive.rule
Hashcat: https://github.com/hashcat/hashcat/releases

Glad you got back in. Its a sad feeling thinking you have lost your coins/tokens.
@cliff-on-crypto how I contact you ?
