I recommend anyone still struggling to start over and follow this guy (https://youtu.be/jZJR4VrUG9U) and to locate the unpacked client. The unpacked client will save you a world of headache because you can avoid using the pkextractor tool. And also finding out if your system plays well with WSL1 before trying WSL2. My personal system seems biased towards WSL2 (MariaDB/MySQL refused to work on WSL1) but we had great success with WSL1 on my nephew’s system. We got him setup in only a couple hours. This is not easy for sure. Every system seems to be different. It took me over 20 hours to figure out everything that is going on here but in the end it’s totally worth it. You got this!
