... however my daily 'bread and butter' program doesn't work atm. It's JPSoft's popular command line extension, formerly known as 4dos or 4nt. Many people run this for their daily Unix-like shell navigation or depend on a huge base of 4dos/4nt/tcc-based batch scripts. Get the free TCC/LE version or a trial for the full "Take Command" here: https://jpsoft.com/all-downloads/downloads.html
I'm running Win10 x64, and the error message is...
SBIE2303 Could not hook NtQueryObject (888)
SBIE2304 Initialization failed for process tcc.exe
Since the bare cmd.exe and even Cygwin's bash runs just fine, I hope it's in the scope of your workload to get TCC running - pretty please with sugar on it
