Linux – How to fix the terminal and Linux files for error 20 on a chromebook

Today, I was trying to access the terminal and Linux files for Linux, but it suddenly all crashed! I got crosh (press ctrl-alt-t on chrome to get there) to act as my terminal with the code "vsh terminal" and "lxc exec penguin — /bin/login -f USERNAME", but the actual terminal and Linux files in the files app are not working. When I try to access my Linux files, it gives me an error message that says "Unable to view Linux Files: Error mounting crostini container", and when I open the terminal, it says "[Error starting penguin container: 20 Launching vmshell failed: Error starting crostini for terminal: 20" I have been trying to get this fixed since the morning but was not able to do much. Please tell me how to fix this! My device is an Acer Chromebook. Thank you!
