already tried using hashcat tool ?

imo it's faster than JTR for bcrypt hashes

+ if you're not familiar with CLI, someone on the hashcat forum make a GUI version, can be good to see

First get deps
sudo apt update

sudo apt install build-essential libssl-dev

Then install john the ripper

sudo apt install git
git clone https://github.com/openwall/john -b bleeding-jumbo john
cd john/src
./configure
make -s clean && make -sj4
check install
cd ../run
./john --list=build-info
./john --list=formats | grep bcrypt

get a wordlist, like from seclists
sudo apt install seclists

and start cracking with wordlist:
./john --format=bcrypt --wordlist=/usr/share/seclists/Passwords/Common-Credentials/10-million-password-list-top-1000000.txt hashes.txt
