Repls suddenly crashing with weird "internal" errors (working fine for months prior)

Repls were working fine for months. Suddenly started crashing. One has this error when it tries to start:

exports.formatters.o = function(v) {
TypeError: Cannot set property 'o' of undefined

and another has this error:


TypeError: app.init is not a function

Looks like other users here are also seeing some weird stuff happening in the last few hours.

If an admin reaches out via my account email I can share the links to my repls.

I solved this by running rm -rf node_modules && npm installin the shell to re-install all modules.
