During descent at low thrust,these crystals will accumulate in the compressor area and bang bang here goes your stall/engine fail.
Rubbish! Microscopic ice crystals "accumulating" in a compressor!
I suggest you take you "carby ice" understanding of jets, or mis-remembered understanding of volcanic ash back to the world of Cessna 172s.
I don't know if you are aware - but the engine anti-ice on a jet engine
only de-ices the COWL (and sometimes the spinner)
It is used to prevent ice build up on the cowl, which then leaves the cowl in chunks big enough to damage the fan. It
does not warm or change the air (or ice or water) entering the engine in any way.
