Sorry, no, they all happened in automatic suite- run and I always at once confirmed the error message to make GUI go on wihout losing time for next one position.
Anyhow, here I have a game- pair out of a match against Lc0CPU, (v32.1, net 3395000) single thread, 3'+1", UHO 2024 900-990cp 6mvs (therefore I wanted to play both engines bookless, to make Absurd do so, I had to take out book.bin of the option field in Cutechess GUI, otherwise it used it even with Bookdepth=0, Bookrandom=0).
This one 0-1 of Absurd was in filter of very interesting wins in IWS- Tool, the speciality is, the game with reversed colours was won by Absurd too

The match was won clearly by Lc0CPU of course (Score of Absurd1 vs Lc0CPU: 99 - 319 - 82), yet here are the EAS- ratings out of this single 500 games- match, showing quite a reversed one picture again, even more amazing with so little number of wins at all, compared to those of the opponent:

In meantime I had another one crash in Fritz 20 again, this time together wit the position, an old test positions ouf of ACT5 (nr.49 there),

[d]4n1k1/8/1b1P3P/1qB3Np/6PK/7Q/p2p1p2/8 w - - 0 1

This one even was (at a single one second try) reproducible as for crashing, after first time in automatic suite, now in infinite analysis, again a crash of the benign kind, that clicking Ok at once makes GUI and engine go on working.

Next one, a Pervakov- study, HHdbVII (+4830.55b6e8), again crash in automatic suite as well as in infinite analysis:

You are right, could reproduce it, thanks.
90% of coding is debugging, the other 10% is writing bugs.
