I was having the same problem, very frustrating.
Easy fix: open the master material in case, disconnect anything from it, for example the Base Color node. Save. Connect it back. Save.

Try to delete the Derived Data Cache folder!
Probalty itā€™s contain some broken cache for shaders.
Itā€™s often happens when you changing unreal version for projectā€¦
Or when you have materials with same names but in different folders.

My unreal engine (5.5) crashes when I try to save landscape layers.

Gets stuck at 0% and I have to end task.

The best solution so far is to change engine versionā€¦

Yeah it was resolved for me in 5.4 or 5.5, donā€™t remember.

Itā€™s the most silly fix in the world, but it helps 100% of the timeā€¦ This happens while saving a material instance, the way to fix this freeze is to open the parent material (master material, and resave it).
