OLED screen ndot working with Pi4 and V2 of SunFounder case

I purchased this pironman case. Assembly was straight forward. There was no oiled display but I continued anyway. I set it up according to section. Ran the config. Then try I’d some changes to the settings and here is where I have an issue. The power switch lights but with out the OLED display not sure if it is working. Set the fan to 30 degrees Fahrenheit and it does come on. The RGB strip turns on. I get an error that says [Erron 121] I/O error when starting OLED.

1.Please check if the OLED screen is properly connected and secure. It is recommended that you unplug and reconnect it.
2.Please check if your i2c is enabled. If not, please execute the command “sudo raspi-config” to enter the settings page and enable i2c.
3.Please provide us with the Pironman log file, which will help us analyze and solve the problem.
The log file path is: /opt/pironman/log
You can execute the command: cat /opt/pironman/log

I2C is enabled (rebooted) and i have tried several times to re-install the screen. No luck
