Kicad stops responding while writing to disk until full

I’m starting to wonder. Are these individuals with nothing to do? A contest to see who can get the most ‘shit’ into forums? Are they paid to help train AI? State actors infiltrating? Criminal organizations?

Probably a tool in the toolkit available to inmates of spam farms.

If there is a known bug related to filenames and/or path, does that means we cannot use KiCad at all?

I am fighting with some extremely weird behavior related to ngspice simulation. Probably such a bug will create problems in schematic and PCB also, not just simulations.
