Blender 2.82a shutting down upon start

Hello!

The portable version of the latest release of blender is acting up on me at launch.
Blender seem to somewhat load, no UI is seen, just the “window”. It then promptly shuts down.
Why the portable version? Because I’m on a corporate PC and I do not have admin rights to install stuff, and it’s a hassle to get the admin to install.

So, what could be the issue here? I’ve used the portable versions since 2.80, without problems.
