Has it always done this? Or used to be okay?

This is only local saves, not cloud, is that right?

What antivirus app do you use? Add EU4.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list. You should add steam.exe and C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2021.8.2/paradox launcher.exe to that list.

You almost certainly have a different problem then.

Above I described how to do it with Windows Defender, if you have any other AV app you should contact their support.
