Yeap a PIA known issue I've been tracking at https://community.amd.com/t5/pc-drivers-software/memory-leak... - Was finally fixed with 24.7.1 and newer.

FYI, can quickly test by running in a standard user cmd: "FOR /L %i IN (1,1,1000) DO cmd /c echo %i" And then can use Bruce's FindZombieHandles from https://github.com/randomascii/blogstuff/blob/main/FindZombi... to check if the and driver (anything really) is leaking.

Some AMD drivers leak handles to every process created. On a build system that creates tens of thousands of process this leaks tens of thousands of process handles with each one creating a zombie process and wasting about 64 KB. This leak can consume all RAM on a powerful workstation in just a few days.
