At the mean time you can try using the experimental Krita with clipping (test build) - #13 by raghukamath and see if it can import the files with clipping masks.
Maybe this is the problem, the clipping mask. I don’t have any program that utilizes clipping mask as the default (PS or CSP per example), but I would bet they are the culprit in crashing Krita.
I thought Krita would give a warning and/or discard clipping mask (or convert to paint layers) when opening a PSD file. Maybe it does but a huge amount of them are causing it to crash.
You could trying making a custom file, specific to sharing here, with your workflow that causes a crash in Krita so the devs could improve the PSD importer (There is no fleeing this beast, an app nowadays has to open PSD files).
