Having the same error when using the debug 0x... from the truffle console...

This is due to the latest update - https://www.npmjs.com/package/truffle

is there a way to revert back to old version :)

Me too. It seems to be wrong linking with package babel runtime.
Fortunately you can temporary fix this problem by running the following command:
npm install -g babel-runtime
In the meantime, we should fix this problem or at least update the documentation immediately.

After a bit of continued testing it seems like you'll want to use truffle v5.1.39 as I was able to get that version to work, so you'll want to do:
<npm uninstall -g truffle>
<npm install -g truffle@5.1.39>

Nope, that version didn't work too.
Installed babel runtime globally as @ngochiencse suggested, work as a workaround.

It worked!

OK, can people try this again with Truffle 5.5.13? Thanks!

[SebGazeau]

With 5.5.13 it works for me !

@dibi91 can you confirm Truffle v5.5.13 resolves the issue?
