well ，actually there is no publicSuffixDomainCache.txt in Users\user\AppData\Roaming\KeePass
actually even KeePass folder is not existed. and i tried to run keepass2 as admin,still the same , no files create.
both of my windows os missing files ,but my linux os works well ,i suppose win10 1809 update break something
edit：download the list manully fixed my issue，but still dont know why keepass2 cannot download it autolly
