I'm experiencing exactly the same crash when I load save files, with exactly the same error messages before the program exits. A few more observations about this bug, in case they might be helpful:

1) I'm running Windows 11 on a gen 11 core i7-11700K, with 64GB of system RAM and an RTX 3060 GPU with 12 GB VRAM, and lowering my graphics settings to only take up half of that on launch did not help.

2) The crash happens 100% of the time in the save files that were apparently corrupted, regardless of what situation I was in when I loaded them. Conversely, files that are not corrupted seem to load successfully every time.

3) As far as I can tell, the corruption happens almost every time when you've saved a situation where you are flying and have had a recent SOI change. I only found one instance of a save that was corrupted where there had been no prior SOI change, and the only uncorrupted files I have where there had been one are a file where I was landed on the Moon and a file where I was back in LLO after that landing. OTOH, a file saved before those, when I was in LLO after having come into the lunar SOI, was corrupted, as was a later save when I was setting up aerobraking after leaving the lunar SOI.

4) Importantly (I think) for purposes of reproduction, I repeatedly loaded several of the corrupted saves without problems while still in the session where I created them. The problem only happened after I had quit KSA, re-launched it, and attempted to load those saves again.

5) I sure hope this can be fixed fairly soon, because it makes flying complex interplanetary missions piecemeal essentially impossible for me

should be fixed in the next build.

I just installed the latest build, and all my saves that were crashing the game before now seem to load normally. Huzzah!
