UE 5.4.4 still crashes during trivial Material Editor operations

Unfortunately even after 4 hotfixes, 5.4 can’t shake off its reputation as the buggiest release in the UE history :frowning:

Even most trivial Material Editor operations will crash the engine. Below is one example from 5.4.4:

The repro steps should be quite simple:

  1. Open any 5.3 project in 5.4 (doesn’t work in fresh 5.4 projects for some reason).
  2. Open any material authored in 5.3
  3. Set material mode to use material attributes
  4. Create SetMaterialAttributes node and hook it up
  5. Create an input on SetMaterialAttributes node

Result: Instant crash to desktop.

I am not sure what the “Send and Close” button is for in the crash window, since I’ve been “sending” this report since 5.4.0 yet it was never addressed. I suppose nothing is really being sent, or evaluated on the other side.
