Webcam not working after resetting Octopi

Camera model
Logitech HD Pro 7890-C920

What is the problem?

After many hard shutdowns of my Raspberry Pi 3B trying to resolve other issues with my octoprint, eventually my webcam stream stopped working. I tried many things like restarting webcamd, editing the octopi.txt, to switching USB ports, testing the camera itself (which was confirmed to work), uninstalling TSD, and even installing octopi on another microsd card and restoring the backup. But now the webcam stream at http://[my pi IP address]:8080/ does not work, and shows a "This site can't be reached" error, and from the webcamd.log shows "libv4l2: error turning on stream: Protocol error". I'm at a loss of what to do next.

What did you already try to solve it?

### Configure which camera to use
#
# Available options are:
# - auto: tries first usb webcam, if that's not available tries raspi cam
# - usb: only tries usb webcam
# - raspi: only tries raspi cam
#
# Defaults to auto
#
camera="usb"

### Additional options to supply to MJPG Streamer for the USB camera
#
# See https://faq.octoprint.org/mjpg-streamer-config for available options
#
# Defaults to a resolution of 640x480 px and a framerate of 10 fps
#
camera_usb_options="-r 1920x1080 -f 30 -d /dev/v4l/by-id/usb-046d_HD_Pro_Webcam_C920_9D9922BF-video-index0"

### Additional webcam devices known to cause problems with -f
#
# Apparently there a some devices out there that with the current 
# mjpg_streamer release do not support the -f parameter (for specifying 
# the capturing framerate) and will just refuse to output an image if it 
# is supplied.
#
# The webcam daemon will detect those devices by their USB Vendor and Product
# ID and remove the -f parameter from the options provided to mjpg_streamer.
#
# By default, this is done for the following devices:
#   Logitech C170 (046d:082b)
#   GEMBIRD (1908:2310)
#   Genius F100 (0458:708c)
#   Cubeternet GL-UPC822 UVC WebCam (1e4e:0102)
#
# Using the following option it is possible to add additional devices. If
# your webcam happens to show above symptoms, try determining your cam's
# vendor and product id via lsusb, activating the line below by removing # and 
# adding it, e.g. for two broken cameras "aabb:ccdd" and "aabb:eeff"
#
#   additional_brokenfps_usb_devices=("aabb:ccdd" "aabb:eeff")
#
# If this fixes your problem, please report it back so we can include the device
# out of the box: https://github.com/guysoft/OctoPi/issues
#
#additional_brokenfps_usb_devices=()

### Additional options to supply to MJPG Streamer for the RasPi Cam
#
# See https://faq.octoprint.org/mjpg-streamer-config for available options.
#
# NOTE: Newer raspi cam modules are reporting as usb devices causing these
#       options to be ignored. Set `camera="raspi"` to avoid these issues.
#
# Defaults to 10fps
#
#camera_raspi_options="-fps 10"

### Configuration of camera HTTP output
#
# Usually you should NOT need to change this at all! Only touch if you
# know what you are doing and what the parameters mean.
#
# Below settings are used in the mjpg-streamer call like this:
#
#   -o "output_http.so -w $camera_http_webroot $camera_http_options"
#
# Current working directory is the mjpg-streamer base directory.
#
#camera_http_webroot="./www-octopi"
#camera_http_options="-n"

### EXPERIMENTAL
# Support for different streamer types.
#
# Available options:
#   mjpeg [default] - stable MJPG-streamer
#   hls - experimental FFMPEG HLS streamer
#camera_streamer=mjpeg
