I'm afraid I can't help you there, that command looks perfectly fine (at 
least on Linux, I have no clue about Windows). However, see below.

What version of HTCondor are you using? The DAGMAN_USE_CONDOR_SUBMIT 
knob was at some point renamed DAGMAN_USE_DIRECT_SUBMIT (with inverse 
meaning, and defaulting to True).

Given that the knob defaults to True, I suppose you shouldn't need to 
set anything (as that would be equivalent to setting the other one to 
False). However ...

Yes, this looks like its caused by the same bug discussed in this 
thread: 
https://lists.cs.wisc.edu/archive/htcondor-users/2022-April/msg00031.shtml, 
which occurs precisely when using direct submit (which became default in 
9.7.0).

What's happening is that HTCondor incorrectly tries to obtain the system 
credentials, while it is running as a user (it's doing a "direct 
submission") and should be getting the user's credentials.

You could try working around the issue with 
DAGMAN_USE_DIRECT_SUBMIT=False, but I suppose that will not work with 
your inline job definitions.
