A new problem... I know you don't officially support Insider builds but, this is a Preview build of Windows 24H2.
-----------------------------------
Edition Windows 11 Pro
Version 24H2
Installed on 05/25/24
OS build 26100.712
Experience Windows Feature Experience Pack 1000.26100.6.0
-----------------------------------
This build appears to break DeskScapes_11.0.1.0-j146-Setup_sd.
I haven't yet tried DeskScapes11_setup_sd or DeskScapes10_setup_sd.
I have purged and reinstalled to no avail.
After installing this Windows 24H2 update Deskscapes will not display a playlist, nor any background I have downloaded through Deskscapes.
I haven't yet reinstalled my graphics drivers.
I'm just giving you a heads-up that something serious is happening with the 24H2 update.
I'll update this if/when I have more info.
Cheers.
