Endless loop of nested subfolders

[AndrewPy]

If you try to copy one folder (or two folders) into itself (by mistake), an endless loop of nested subfolders will be created until the app is stopped.

(v.6.7.3 Pro with Android 9)

it shouldnt be possible to copy a folder into itself, please tell the exact steps for reproduction

[AndrewPy]

Create a folder "Test" with two subfolders "Test1" and "Test2".
In "Test2" create one subfolder "Test3".
(Make sure that "Test3" is a subfolder of "Test2".)

Now select the Folders "Test1" and "Test2" and copy them into "Test3".

Can confirm this issue still persist on 6.10.1.

Should be implemented as showing a warning like
"The copy destination folder cannot be a subfolder of the copy source(s)"

Dunno if symlinks are supported on android tho

It is still an issue now.
