MissFaylyn A python37_x64.dll crash is typically related to CPU Turbo Boost (whatever it happens to be called), although this error can have other causes. So please boot back into BIOS and look for any other setting that has Turbo in the name and could conceivably be affecting the CPU. The thing is that the Intel Turbo Boost Technology setting may be only one—the board may have its own independent setting and include the Intel one because it's required for the platform. Most boards do specifically have a "CPU Turbo Boost" setting that, as far as I can tell, is something the manufacturers apply themselves, meaning it's probably not the standard Intel tech.
The problem for me is that it's difficult to find the exact BIOS settings for a particular board; even the manuals don't help because they don't always include updates to the firmware. And each board has its own settings, even those in the same class and from the same manufacturer. So since I can't see what you're looking at, and I can't find documentation that I can trust, I can't tell you whether that's the right or only setting, only that I suspect it may not be.
If you can't find any other setting, please do a clean uninstall and reinstall of Sims 4 and the EA App, as described in the solution of this thread (for a different issue, but the process is the same):
[CURRENT ISSUE] Sims 4 DLC shows as installed, won't load in-game | EA Forums - 11831673
This helps with most of the python37_x64 crashes that are not CPU turbo-related.
