TypeError: Cannot read properties of undefined (reading 'length')

There seems to be an issue with your TypeScript config file, as TS crashes when trying to process it.

Without a reproduction this isn't otherwise actionable to us.

Thank you for the direction. I start debugging it and find out it was looking for out || outFile property from my tsconfig, so I added one, but now it fails with:

Please provide a reproduction; the out/outFile being omitted shouldn't cause TS to crash, nor should the newly shared stacktrace. But without further insight into your setup, this won't be actionable.

I found out what was causing it. After going through all dependeces again I noticed that @nx/angular was 17.1, not 16.2 like the others deps. After changing it to 16.2 it start building again.
