From my understanding, the issue with the GE-9x is a durability problem with a component in the compressor that GE itself is manufacturing. It's not good news but it shouldn't be a showstopper.

  Here's the best link I could find on the problem: https://thepointsguy.com/news/boeings-777x-delays-engine-issues/ https://thepointsguy.com/news/boeings-777x-delays-engine-iss.... High-bypass turbofans are finicky things. It seems likely there will be more teething problems in that area. The GE-9x increases the bypass ratio by 11% from 9 to 10 over the GE-90 based on comparison of specs published in wikipedia. [1,2] So the interesting question for launch is what else pops up.

    If you are interested in turbine engines, I highly recommend this guy's youtube channel as he will teach you everything you ever wanted to know and more about how turbines work. This video is about the compressor and it's actually a very simple component. Pretty much the only thing that can go wrong is that metal fatigue starts to form where the fan blades meet the hub. I suspect that the size of the compressor is resulting in larger centrifugal forces causing fatigue to occur quicker. https://www.youtube.com/watch?v=CXSi4GXUojo https://www.youtube.com/watch?v=CXSi4GXUojo
