Sync iCloud issue

Three days and I still don’t know what to do. My files and photos from iCloud don’t sync with MacBook. I can see them but they cannot be downloaded. I can download them in iPhone and iPad, but not into Mac. I tried everything - sign out from Mac, restart and so on and nothing changed. What helps, is only restart my Wifi, after that it works but until i shutdown (close) my Mac. After waking up, it’s doing again - cannot download from iCloud (even through web iCloud). Don’t know what to do… And don’t know but may be it has happened after new macos 15.1
