What happens if trying that to ignore an ordinary on-disk folder that gives you no access per ls -ld?
I tried a chmod 0 on one, and it was ignored, except for the lstat that’s done to exclude block devices.
This check is not logged, but the filtering is, e.g. at About → Show log → Live → Verbose. Example:
$ ls -l /home/erik
total 8
-rw-r--r-- 1 root root 5 May 13 20:04 ordinary_file
d--------- 2 root root 4096 May 13 20:06 pCloudDrive
$ ls -ld /home/erik/pCloudDrive
d--------- 2 root root 4096 May 13 20:06 /home/erik/pCloudDrive
$ stat /home/erik/pCloudDrive

The low-level way to see what’s going on at Linux system call level is with strace. That may be next.
Stepping up a level, knowing your results on the ls and stat tests I showed above might be useful.
Is Duplicati running as root or as the /home/erik user? Please test access with whatever Duplicati is.
The live log can give you a better view of the Duplicati-level error too, by clicking on the line of error.
Here’s the error if I stop filtering out /home/erik/pCloudDrive. After the one-line summary are details:

Is this pCloud Drive for Linux? If not, what is it? That may impact how hard it is for someone to test it.
