Check the contents of/home/yellowtent/box/VERSION . Is it 7.4.3 ? If so, you can run the commands below and make it work again . After you get it back, snapshot the server and upgrade ubuntu when possible.

curl -sL https://nodejs.org/dist/v16.18.1/node-v16.18.1-linux-x64.tar.gz -o /tmp/node.tar.gz
tar zxvf /tmp/node.tar.gz --strip-components=1 -C /usr/local/node-16.18.1
rm /tmp/node.tar.gz
ln -sf /usr/local/node-16.18.1/bin/node /usr/bin/node
ln -sf /usr/local/node-16.18.1/bin/npm /usr/bin/npm
