Quartus 22.4 crash "Internal Error: Sub-system: VRFX2, File: /quartus/synth/vrfx2/vrfx2_xmr.cpp"

When running synthesis on a design that synthesizes (and compiles) fine under Quartus Prime 19.2, I consistently get the following crash happening. It also crashes similarly under Quartus 23.1. Any ideas please?
