New to Octoprint and rPi needing help with setup

What is the problem?

I purchased a rPI 3B+ to connect my rPi to my ender 3. I downloaded octoprint and followed the formatting setup to a tee. I got things working and I got into octopi.local and it booted followed the setup and everything. I had to leave so I closed out of my browser and shut off my printer. Came back later and tried to get into octoprint through octopi.local again and nothing happened It loaded for probably a couple of hours. And now I think I have dug myself a hole trying to fix this because I know very little about rPi's and I do not know what I am doing whatsoever. The ACT light will not flash at all now anytime I put an SD card in.

What did you already try to solve it?

I have tried formatting two different SD cards, I have tried plugging it into a monitor with keyboard and mouse but its not displaying anything. I tried SSHing into the rPi but that took forever. I have changed the power supply.

Complete Logs

octoprint.log, serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support! Not log excerpts, complete logs.)

No logs available. sorry...

Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible

I think I was on the latest version of both Octoprint and octopi not sure though because I never got that far to check. I have an Ender 3 with a skr v1.3 MKS Gen L. I am using a MacBook Pro macOS Catalina.
Any help would be greatly appreciated. any advice might have to be dumbed down and explained how to do since I am beginner with this stuff.

I guess it's a power related issue. Your printer might be powered via usb from the pi when it's turned off.
Try if the pi boots without any usb devices connected.

If the pi works again try this so it won't happen again.

Also you should use a sufficient power supply for the pi (not a phone charger or a usb port of another device)

I have tried booting without connecting to the printer. Still no booting just the red power light is on. rPi is powered by printer the Gnd and 5v on the pins have tried powering it and booting from a different power supply. Any other suggestions @PrintedWeezl?

the only thing I would test before rma-ing it is to run a standard raspbian image...
maybe your image is corrupted or something so let'S just test raspbian and see if it boots.
