Studio Not Opening

Hi there, 
I just updated my version of s4s.
I've worked through the troublshooting forum and cannot resolve the issue.
It simply opens, doesn't load, then closes. (pictured below).

I looked in the Event Viewer under Window Logs, and there are two errors happening. 

1. is an application error:

Faulting application name: S4Studio.exe, version: 3.1.3.9, time stamp: 0x5faefca5

Faulting module name: KERNELBASE.dll, version: 10.0.18362.1139, time stamp: 0x6a8e6b97

Exception code: 0xe0434352

Fault offset: 0x00114662

Faulting process id: 0x1530

Faulting application start time: 0x01d6c2536e7ee4a4

Faulting application path: C:\Program Files (x86)\Sims 4 Studio\S4Studio.exe

Faulting module path: C:\WINDOWS\System32\KERNELBASE.dll

Report Id: c763579b-7576-47f3-898d-665581b527ef

2. is a .NET runtime error:
