This information is too generic to be helpful, since the end of day is probably the largest section of code in the game. There is a Debug mod which can reveal the error message rather than the game crashing. Note that just because the game will not crash does not mean the problem is gone, so it is possible to permanently corrupt your data if you save after an error.
