Never Install the package Success(UNITY 2019 & 2022)

[jasjang]

I've tried many times.
It always show fail to import the example.

"A meta data file (.meta) exists but its folder 'Packages/com.htc.upm.wave.openxr.toolkit.samples/Editor' can't be found, and has been created. Empty directories cannot be stored in version control, so it's assumed that the meta data file is for an empty directory in version control. When moving or deleting folders outside of Unity, please ensure that the corresponding .meta file is moved or deleted along with it. "

Could you please kindly restore the install way back to Register source server
