Hello. I launch FreeFileSync from the windows task manager. I get an error when accessing a network folder. I have full access to the folder.

from the windows task manager

I have full access to the folder

Are "task manager" & "I have" one in the same?
As in does task manager & "I" run with different credentials?

If outside of task manager, if "I" (you), who has full access to the folder, "manually" run a sync (so fire up FFS set left side to c:\needs 2 backup\, & right side to \\192.168.7.5\backup_test), does that work as expected?

I ran the task from both my account and the system account.
Everything worked before updating to version 13

That's how I'm configured

I didn't see "error_not_authenticated" specifically, but maybe something in here, WNetAddConnection2?

Everything worked before updating to version 13

If you (update to 13.1, or) revert to 12.5, does your sync again work?

I found the problem. I did not run the task with the rights of another user. Thanks everyone for your help
