Shaders recompiling at each launch when starting Isaac Sim 4.2 from python

It seems that launching Isaac Sim 4.2 experience from cmd on Windows with the DX12 backend results in extremly long loading time, as result of isaac recompilng RTX shaders at every launch. Ths issue does not happen when launching issac sim using Omniverse launcher, or launching issac sim from python using the --vulkan flag. however --vulkan is much slower for complex scene with large number of objects. Any suggested workarounds?

Update: the issue happens specifically when trying to launch isaacsim kit experience from cmd using:

C:\Workbench\IsaacSim4.2> isaacsim omni.isaac.sim (slow startup)

However launching a simulation app from a test python script startup time is fast using DX12 backend, eg
C:\Workbench\IsaacSim4.2> .\isaaclab\isaaclab.bat -p .\test_app.py (works correctly)
