Problems with recording

I am using Mixxx for very lonjg time n ow, but when i installed an trustfully anti virus i was having some poroblems with recording, then i completely reinstalled my pc, i completely whiped away my hard drive and reinstalled windows then i installed mixxx again but the same porblem happened again???

Problem is the programm says it has not the permission to write at the folder (the folder is not blocked and to be sure i started mixxx administrator mode with the administrator account on my pc)
Also there could be the problem that i don#t have enough free space, but there are like 2TB free so i don’t think that’s the problem to

Screenshot of the Error:

Are you sure the parent folder of the directory you want to use/create exists?

Did you install the AV? Maybe whizelist the the recording directory for testing.
