    Resolution Note (fix version 2022.1):

    Fixed in 2022.1.0b1

    This issue can be worked around by adding this attribute to generated .vcxproj file:

    <AppxBundleAutoResourcePackageQualifiers>Language|DXFeatureLevel</AppxBundleAutoResourcePackageQualifiers>

    Once you upgrade to a Unity version with this fix, make sure to delete the old generated .vcxproj file as Unity will not overwrite it.
