Sorry.
The game version is 1.10.984.0. I was aware of this when downloading the MODs since some of them were version-specific.
I wasn't able to run anything before my first attempt with crashes. I've played the whole game already on PS5, but since I have a PC now, I wanted an experience with MODs. That's why I started with all these 50+ MODs (and from what I've read, many MODs can compromise the save file, so I didn't want to add something like this later on and have the chance to corrupt my save file).
On my first save, I was able to reach Concord when the crashes started, but I didn't notice that I was playing with SimSettlements and SimSettlements2, which caused a conflict. So, I removed SimSettlements and started a new save. On this new save, it's crashing as early as the Vault-Tec salesman offering Vault 111.
Also, my FPS is consistently above 70.
