git for windows hangs on various commands

[heineckgit]

Using git version 2.49.0.windows.1
Frequently exec calls to git from AMD/Xilinx Vivado (various versions) in a tcl script will hang. According to Process Explorer, the command varies but the hang is always at git.exe+0x1410. It's state is "Waiting", the Wait Reason is "Executive". This will happen on 50% to 90% of the Vivado invocations. Vivado is being invoked by Hog.
I've looked at the page https://gitforwindows.org/debugging-git.html and I'll give it a shot if no one has any ideas what it might be waiting for. Debugging git really is very far outside my job responsibilities.
