Process Explorer 17.2 fails to start.

I use Chocolatey to update my instance of it. And I tested with a clean download from https://download.sysinternals.com/files/ProcessExplorer.zip. It has the same issue. So I ruled Chocolatey out of beeing the cause.

Here is my eventlog entry of the issue:

Faulting application name: procexp64.exe, version: 17.2.0.0, time stamp: 0x6ad089e9
Faulting module name: KERNELBASE.dll, version: 10.0.26100.9711, time stamp: 0xfb9071fb
Exception code: 0xc06d007e
Fault offset: 0x00000000000c408a
Faulting process id: 0x1EC0
Faulting application start time: 0x1DD6B98B42B7A79
Faulting application path: C:\ProgramData\chocolatey\lib\procexp\tools\procexp64.exe
Faulting module path: C:\WINDOWS\System32\KERNELBASE.dll
Report Id: 34ab889c-7efb-4885-841e-00df1d84d445
Faulting package full name: 
Faulting package-relative application ID: 

I have also made sure that Windows Defender excludes the process.

And here is what systeminfo shows about my machine:
