yarn start command failed with exit code 127 - node.js

Question

Every time I try to start my project as usual using "yarn start" I get the "Command failed with exit code 127" error. I've realised I started to get this error once I've updated my iOS to Monterey v12.6.1 . My node version is not compatible with the yarn it seems like.
What have I tried to fix this:
I have tried to upgrade/update my node version.
I have uninstalled manually node/npm and yarn and reinstall them back with node version 16.0.0
I have deleted the node_modules and package_lock.json
I have had run the command "yarn" and every other update/upgrade command
Everything that I have tried failed.
This is the yarn error log:

Any other idea how to sort this out would be much appreciated.
Thank you for your time!
