"Your Windows version is not supported" 3/17/26

Today at morning I launched game without any issues. Then I turned pc off and turned it on again few hours later. Now I am unable to launch game, no matter what I do. 

• When I uninstall using \Battlefield 6\EAAntiCheat and then use repair, it installs even older version from 26.01. 
• When I update, I get version from 07.03.
• When I repair game, I get version from 18.03. When I launch game it takes long time to check for updates, starts Javelin and then launches game. Unfortunately it also downloads version from 07.03 which is bugged and consecutive launch attempts instantly give me error. I have to unpack RAR and replace these 3 files every time. Tried setting them to read only but game replaces them anyway.

Issue was not present yesterday. I launched game yesterday and I launched it today without any issue. BUT there was update today morning. Since the update game is broken.

update: after few attempts my files stopped being broken. They are stuck at 18.03 and do not update to old version anymore. Not sure what changed. I repaired game again, launched it again, it downloaded broken files again and then I updated it using \Battlefield 6\EAAntiCheat just to make sure that it downloads bad version from 26.01 again. But it downloaded 18.03 and it is working fine now.
