You say the error has already occurred several times?
Can you confirm that it is an unmodified variant of Stockfish?
I'll explain how far I understand the error so far: BotLi doesn't let the engine continue pondering when it starts using syzygy or gaviota. The idea is that the engine doesn't continue pondering unnecessarily when it's not being used anyway. This is of course not so important in a bullet game, but in longer games it can be several minutes. To do this BotLi lets the engine analyze the start position for 1 ms without pondering. And this is where the error seems to happen. That's why python-chess expects an answer to the analysis of the start position, but in your case it gets the analysis of a completely different position.

Yep, it is a unmodified variant of Stockfish, git cloned from https://github.com/official-stockfish/Stockfish.git and compiled by the following commands:
cd Stockfish/src
make -j profile-build ARCH=x86-64-bmi2 COMP=mingw

Yes... For the past 4 days I have kept either of my bots (EmptikBot, Emptik-AI, Emptik-AI-2) online overnight, and in the morning same thing..

At the moment I have no idea why this is happening to you. My wild guess is maybe it has something to do with Windows and that's why it's not happening to me. On the other hand, you are probably not the only one using BotLi on Windows.

Yes I use BotLi on Windows and it didn't happen to me...

Happened again, seems to only happen when Syzygy starts being used...

Could be that 6-man Syzygy takes up too much ram (I have 32GB) and the engine crashes due to that?
At this point, the position is at Depth 113, engine is still running..

Any idea on why this could be happening? Does my PC (32GB) not have enough RAM to handle 6 Man Syzygy or anything? Seems to be only recently happening after I implemented 6 man..

That's an interesting information. Maybe you don't have all 6 men tablebases and I don't handle that correctly in BotLi? That's something I will check when I'm back home.
It has nothing to do with the hash, the engine isn't crashing it is just not in sync with python-chess.

Nope,
I have all the 6 man tablebases..
My 5 man is in another directory also linked..

At this point if 6 man is giving such problems you can try with 5 man and check if the problem persists. I use BotLi both on Linux and Windows and never had a similar problem...
Actually there is not even a 1 elo benefit since NNUE era to use 6 man, thats why I make this suggestion...
Instead of 150 GB, 5 man are only 1 GB and you can use online 7 man syzygy....
