What application is it that is showing up black? Some applications utilize security features to prevent viewing from remote access. I'm wondering if that's the case here? My other guess would be the video driver on the remote device.

i agree with @PathfinderNetworks
without knowing what the application is that doesnt work we really cant help
ive tried googling the image in the taskbar but no results
also exam applications as @PathfinderNetworks explained wont work due to security protections

[Pallaroid]

The application is star Money. It is a banking software for managing multiple bank accounts. Is it then possible to view these via RDP? I cant Connect by RDP because Windows 11 Home.

[si458]

@Pallaroid oh right yes the chances are they have security in place that detects things like remote control software,
and if present they black screen there application.
sadly i dont think you can enable rdp with windows 11 home sadly apart from upgarding to pro
but win 11 pro oem keys are cheap to buy if you know where to look!

the only other thing you can try is customise the meshagent like change its name, company, image, etc...
and then uninstall and redownload the new customised version and install it
then see if its still a black screen

https://ylianst.github.io/MeshCentral/meshcentral/customization/#agent-branding
use agentCustomization to customise its name and location and service name
then use agentFileInfo to customier the data about the file like company name, copyright, icon, etc...
