Alright, I don't understand a thing! :D
Why would you have a Windows Defender exclusion that excludes "MsMpEngCP.exe, MsMpEng.exe", in other words: itself? Are you sure that does something or is it just placebo? I can't imagine this having any effect.
The "FreeFileSync.exe" exclusion is the old one, right? The one I thought already fixed this issue? It didn't?
I'm not sure if excluding "FreeFileSync_x64.exe" is needed, but maybe it is. FreeFileSync.exe calls FreeFileSync_x64.exe, so if Defender excludes whole process hierarchies, then excluding "FreeFileSync.exe" should suffice. If it does not, then only excluding "FreeFileSync_x64.exe" is needed because this is the "real" thing.
Hello. Joining late. I have the same issue (with files of all sizes):
