ArcGIS Pro will not start anymore

[BillSmith]

Hello,

I maintain an application that uses the ArcGIS Pro SDK, so I am often installing/removing different versions to compile against.  The lasts time I tried to install 3.0, it wouldn't start.  So I checked ArcGIS Pro and it wouldn't start.  I've tried un-installing, repairing, cleaning the registry, wiping all files on the hard drive related to PRO.

Nothing works.  I just keep getting this in the Event Log.

Faulting application name: ArcGISPro.exe, version: 3.0.6.36057, time stamp: 0x6216d2c0
Faulting module name: KERNELBASE.dll, version: 10.0.19041.4717, time stamp: 0x16b0a901
Exception code: 0xe0434352
Fault offset: 0x000000000003b699
Faulting process id: 0x87c0
Faulting application start time: 0x01dafa07bc789553
Faulting application path: C:\Program Files\ArcGIS\Pro\bin\ArcGISPro.exe
Faulting module path: C:\WINDOWS\System32\KERNELBASE.dll
Report Id: c57fb378-b77d-4d0d-beb7-09cd267877ed

I was about to call support, but I thought I would post here first.

Thanks,

Hi @BillSmith 

Sorry to hear that you are having this issue. Based on the error message you quoted above here is the respective Microsoft page around the KernelBase.dll

If you have not attempted a clean uninstall (see documentation below) I would then consider the link above if possible.
