The errors related build are common and one of them is segmentation fault.

I am wondering why I get these errors often and also why they get solved automatically sometimes on next build after either running idf.py clean/fullclean etc or building other project from the example projects.

Do anyone has an idea?

Segmentation faults shouldn't happen, and especially not ones that randomly disappear... If I were you, I'd run a memory test on the RAM (and perhaps the HD/SDD) of your build machine; you may have issues there.
