PSUBST issues with Win10 2004 ?

I'm using a batch file to substitute specific folders with drive letters for ease of use, eg:

psubst /p h: "D:\Documents"
psubst ...

So far I needed to run this file once after a major windows update.

Since the Win 2004 update, the substitution is not permanent anymore, and I need to rerun this after every reboot.

Anybody has encountered the same problem?

I am using: "TCC 22.00.41 x64 Windows 10 [Version 10.0.19041] "
I had a similar issue after a major Windows update. But after I re-created the persistent registry entries they work consistently.
The PSUBST functionality is a Windows feature, not a TCC feature. TCC makes it easy to take advantage of.
Look in your registry for "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\DOS Devices"
