@lightsaberluke yes, system is tricky sometimes
if you had used the install or upgrade script it would have handled this problem for you
see https://github.com/sdetweil/MagicMirror
but you can use one of the selective node tools
i recommend n
do this
sudo npm install n -g
sudo n 22.14
hash -r
node -v
you should now have node 22.14 or 22.15
now
cd ~/MagicMirror
npm run install-mm
