When I enabled the camera in the config.txt of the raspberry pi, it asked me to restart, but then it got hung at the "welcome" page. This happened to many other people in our class, so I researched a lot of different ways to fix it. I actually learned a lot of commands on the Raspberry Pi that I didn't know existed including, "alt + print screen + o" shuts down the pi and "alt + print screen + b" reboots it. I then learned that if you press shift before the black screen pops up, you have access to change the config.txt. I attempted to change some of the lines and reboot the pi multiple times, but none of the ways worked.
Challenges I encountered include the initial problem of the the pi being hung and none of my research actually working. I used lots of websites including: https://www.instructables.com/lesson/Navigate-the-Raspberry-Pis-Software-Part-2/

These links gave many options on how to fix different problems, none of which gave ways to fix our specific problem. I tried many different options but none worked, so we will most likely have to wipe our sd cards. This teaches us to make sure to back up all of our data, as basically none of us did that. BACK UP YOUR RASPBERRY PIs!!
