If using Money Sunset, apply the patch described in what is currently the first post in this forum.
I am not saying that this next thing is a likely cause or fix, but might as well try it:
I suggest you open any file you can, such as Sample.mny.
You can do that by going to your Money install folder, right-clicking Sample.mny, and choosing Open.
Go to Tools->Settings->ProgramSettings and set the (GeneralDisplay:)StartMoneyWithThisPageOpen:AccountList.
Close Money.
Then open the problem file once or twice.
Then Tools->Settings->HomePageDisplaySettings and Remove the Investment Performance module. If you still have a problem, remove everything. If the problem goes away, you can add things back until the crash does not happen. Add back in the other things
you want on the home page. Let us know which was the problem module.
