webpack-cli: RangeError: Invalid string length

Describe the bug

I’ve started the migration to webpack@5 and from what I can summise it seems that the compilation is able to pretty much finish, but than it fails with following error.

By what the linked sources are about I’ve tried to set stats: false, however nothing changed.

What is the current behavior?
