What is the problem?
Octoprint will only connect to ender 3 V2 as long as the ender is powered up first and then the raspberry pi gets plugged in second.
What did you already try to solve it?
Starting the ender then plugging in the pi allows the ender to do a hard reset of the baudrate but does not allow me to keep the pi plugged in.
Have you tried running in safe mode?
Yes i have tried safe mode with no change.
Did running in safe mode solve the problem?
No change with safe mode.
You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

Could you please share the bundle?
You find the systeminfo bundle below the systeminfo. It's a zipped file.
Backpowering is likely the issue. Try this:
First of all this whole tutorial isn't a mandatory mod - you just need it if you run into issues (weird things are happening and you've already ruled out the more common suspects) or if the always running fan and illuminated display (even when the printer is turned off) disturbes you.
I'm starting with the why part:
If you connect a 3D printer via USB to your Raspberry Pi it can lead to all sorts of power related issues.
Most of the time those issues occur only if you turn on your pi before …
This will mean the printer is not affected by plugging in the Pi before it is turned on.
Thank you everyone that tried to help. As of today, I had an octoprint update alert and I upgraded it and this seems to have fixed the problem. I am unsure on what the upgrade was as the version of octoprint still reads as 1.6.1.
Sorry to have not replied to this before but I have already had the tape mod applied to the USB and that did not change the outcome.
Here is the system bundle once it has been fixed.

Interesting, the errors in the log indicate that your printer stops responding.
I have noticed that but it has never affected the prints in any way once it is properly connected.
