This week has stopped synchronisation of iCloud Drive and iCloud Photos on my Windows PC. I've found that new version 15.3.138 is unable to connect to iCloud. I've restarted PC several times and checked iCloud app settings. After several restarts iCloud app was unable to even log me in and all local data from iCloud Drive and Photos were deleted.
Has anyone similar problem?
iCloud 15.3.138
Windows 10 22H2 19045.5131
Windows, Windows 10 (19045)
RESOLVED: Sometimes the solution is... just in front the nose. For years I used as my login name my iCloud email address (like mynickname@icloud.com) and as it was for long long years, I thought it's my primary login name - and it always worked quite well. But in reality my primary login name is my private email (like myothernickname@gmail_or_yahoo.com) that I used when I created my iCloud account (sometime in mid of 2010's).
So the solution (at least for me) is: DO NOT LOGIN with your iCloud email alias (something@icloud.com) but LOGIN with your primary account login name (your_original_login_name@otherdomain.com). And now iCloud app for Windows works!
And it was all the time in front my nose: when I was logging to iCloud via web browser, I could notice that primary login name (not alias) was written below my name...
What I understood, Apple has changed recently somehow it's terms and conditions and the one and only way to login is via primary login name, not via any iCloud alias.
Hopefully this will help you.
I’m not sure. My email was already in lowercase. Earlier, while training an AI model, my CPU overloaded and it accidentally started uploading some iCloud Drive files. It had finished scanning everything and was just waiting to start the upload—but it got stuck for at least three days. Then, suddenly, it moved again. After that, because some files changed, it went back into “scanning for uploads” mode. It’s awful. I really wish they’d speed up the scan/upload process. iCloud for Windows seems to slow down the more files you have, and in the end it drags out uploads and downloads by days. I hope they release a big update soon.
I am having a different issue with this 15.3.138.0 on Windows 11 Preview (Dev). When Windows initializes, I get a message that "Files\WindowsApps\Applelnc.icloud_15.3.138.0_x64_nzyj5cx40ttqa\icloud\iclouddrive.exe" was not found.
Changing the login from "Mail@gmail.com" to "mail@gmail.com" helped. Thank you.

J’ai essayé de faire la mise jour vers 15,3 et je n’y ai pas accès. Je voudrais pouvoir l’installer.
Wow this is dumb, but yeah worked for me too. Sign out and then login with your email in lowercase, then everything works...
Had the same error as you in my logs.
