Octoprint TouchUI Webcam Problem

Camera model
Pi Camera V2.1

What is the problem?
After installing a touch screen my webcam stops working.

What did you already try to solve it?
Backup and restart process to find out exactly which step killed the camera.
I've been following this tutorial - https://howchoo.com/g/ztu5owjhytu/3d-printer-octoprint-touchscreen
Step 9 does me in.
Specifically after I install the driver for the touchscreen. - http://www.lcdwiki.com/3.5inch_RPi_Display

When I rolled back to my backup my webcam works fine. I just don't know what is turning it off in this process.

Logs (/var/log/webcamd.log, syslog, dmesg, ... no logs, no support)
When i try that command i get access denied. Sorry just not sure what to do there.

Additional information about your setup (OctoPrint version, OctoPi version, ...)
I've been running my Ender 3 Pro since about June and have had Octoprint with a webcam since about August. it is a Raspberry pi 3 B+ and i updated everything on it before this process. Webcam has worked flawlessly until i installed the touchscreen.

Any help would be greatly appreciated.

I am having the exact same issue with the PiCam v2.1. Once I connect the touch screen & install TouchUI, the camera stream stops loading.

/var/log/webcamd.log shows the following:
