Is there an easy way for me to test this on my setup or should I better wait until this is released?

The fix for this issue has been shipped in the latest pre-release (nightly) build of the Python Environments extension which you can now test!

How to install the pre-release version:

Open VS Code
Go to the Extensions view (Cmd+Shift+X on macOS / Ctrl+Shift+X on Windows/Linux)
Search for "Python Environments"
Click on the extension to open its details page
Click the "Switch to Pre-Release Version" button (next to the Uninstall button)
Reload VS Code if prompted
How to verify you're on the pre-release:

The extension version should show a pre-release identifier (e.g., 2026.x.xxxxx with a timestamp)
On the extension page, you'll see "Pre-Release" badge and the option to "Switch to Release Version"
