I have attempted making a new project multiple times, and each time the VRCUrlInputField script is not properly imported or available until I click the Reload SDK action. This is a consistent import failure and will likely confuse users trying to import use external assets that depend on URL inputs who neglect to, or don't realize they need to, reload the SDK.
It'd be nice if the import for that particular script would work consistently, or maybe have the import process implicitly do a Reload SDK action once after the regular import process is completed, just so the script is available.
In the old import method, this failure occurred probably around 30% of the time, but with VCC it appears to be reproducible 100% of the time for my testing.
