Strive is currently distributed with a normal executable, which doesn't log anything when it crashes upon a substantial error. There is a Debug mod(https://itch.io/t/1137280/debugmod-v10d) which will provide error messages and avoid crashing by aborting smaller sections of the game with errors rather than aborting the entire program. The percentages are not correlated to any specific features, but the first few error messages will likely indicate what went wrong, followed by an avalanche of errors resulting from parts of the game being aborted.
If I were to guess, I'd say that the cause was the mod folder name, as Aric's Expansion references the contents of the folder as "AricsExpansion" and anything else will break a lot of things. When downloaded from GitHub the name of the folder is altered, which often causes problems. Most other common problems don't quite fit your report as they tend to have errors reported by the mod system or crash the game upon starting.
