change the settings, mainly the format album to most basic and the download path to most basic...

[A1derLake]

Still doesn't work after reducing the format album to just "Albums/{album_title}/{artist_name} - {track_title}" and the download path to "D:\123".

[RyanThaDude]

Try enabling LongPathsEnabled in the registry:

Goto: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem, Look for LongPathsEnabled, double-click on it, set the value to 1.

i can confirm downloading with CLI does not work today. (erasing /u part or just u used to work, not now.) It ends up with TypeError: sanitize_filename() got an unexpected keyword argument 'validate_after_sanitize', (does work with gui). (Im on Windows 10).longpaths always but issue is somewhere else.

[A1derLake]

LongPaths is already enabled, but still doesn't work

[orbittwz]

other albums do work?

[A1derLake]

Yes, and according to my observations only these Mahler albums (which have super long file names) don't work.

[orbittwz]

Maybe the stream comes corrupted because you are using a 3rd party program?? idk really how the Tidal API parse those tracks...

[A1derLake]

What do you mean 3rd party program? Do you mean like some other application is interfering with the downloader?

[orbittwz]

I mean that this program is a 3rd party program...

[A1derLake]

Oh ok sry for the misunderstanding
I'll try to run it in a virtual machine tmrw.
