The screen cannot be captured at the moment. This is probably due to fast user switching or a disconnected / minimized Remote Desktop session.
Solution
From our googling result, here are solutions which you can follow,
• Ensure you are using the latest version TeamViewer, preferably both side are having the same version.
• Using Registry Editor, add a new DWORD with value name DisableDuplicationAPI and value number as 1. You may add this on the computer which you are accessing to.
• Set your TeamViewer as Windows service. To enable this, go to Extras > General and check the Start TeamViewer with Windows.
Next, maintain the password for unattended access. Once done, user can access with this personal password or the password on the initial screen.
• [TeamViewer as service] From Windows service, double click on TeamViewer and under Log On tab, check Allow service to interact with desktop.
• Open TeamViewer, go to Extras > Options > Advanced > Show advanced options. Under General advanced settings, check the option Enable enhanced multi user support [for Terminal Server].

• Use server ID when connecting to the TeamViewer. You can click on the blue bulb icon to get the ID.
The screen cannoot be captured at the moment. This is probably due to fast user switching or a disconnected/minimized Remote Desktop session.
This is because the TeamViewer service cannot gain control of the desktop because Windows is not displaying the screen to the console session [as it’s being outputted to the RDP or fast user switching session] or TeamViewer isn’t running as a service and therefore cannot connect to the afore mentioned sessions anyway. To fix this, ensure that TeamViewer is installed as a service, then go to Windows Services, check the properties of the TeamViewer service [right click -> Properties] and check the tickbox to Allow service to interact with desktop on the Log On tab.
❗ Note: There’s also talk on the internet that you’ll also get the Screen cannot be captured at the moment error if you install TeamViewer over an RDP session. I’ve not verified that myself.
I'm a home user and have used Teamviewer for a few years. I have several different computers that I remote into and am fairly familiar with things.
Recently I bought a mini PC that has no screen. [Win10, 1.3Ghz processor, 2GB ram - basically a tablet without the screen]. My plan was to remote into it with TV, which I can do. However the screen constantly flashes the error "The screen cannot be captured at the moment. This is most likely due to fast user switching or a minimized Remote Desktop connection". Remote Desktop is not enabled and has never been used. This constant error/flashing screen prevents me from accessing any of the TV settings at the top banner controls.
Two other interesting bits of information: 1. If the mini pc is connected to a Television or monitor the error does not appear 2. If I use my android phone to remote into the mini pc the error does not appear.
I'm using TV 10.0.45471 on both computers.
Any solutions? Obviously I think this has something to do with the fact that the mini pc has no screen, but I don't know what to do about it or how to trick TV into thinking that the mini pc is connected to a monitor.
If i recall someone had this issue previously and the resolution was to connect an adapter of some sort to one of the video outs: IE a VGA to DVI "plug"
Thanks for the reply but that's not really feasible. I only have a HDMI out for the monitor, and I find it strange that a screen sharing service would require another piece of hardware. I love Teamviewer but I'll need to look into another solution if the only way around this error is to add an adapter like that.
For future reference it does appear that the only option to resolve this is to use a video dummy plug, in my case an HDMI dummy plug/emulator. Officially Teamviewer does not support headless computers, per TV technical support.
