Currently, I am trying to setup anydesk to remote support onto a pi going to be used in kiosk mode. I have anydesk installed and setup so that I'm able to connect but at the moment unable to create a new session or open up the normal window to view the settings panel to setup the custom settings I need.
I've run through and ensured all libraries and up to date which they all are but still unable to open anydesk properly.
I have run into similar problem; The official https://anydesk.com/en/downloads/raspberry-pi source does not seem to work on my Pi 4 (with the most current Raspberry Pi OS). I managed to make it work by following this guide https://pimylifeup.com/raspberry-pi-anydesk/ , it installs a specific version of Anydesk (also seen here https://linuxhint.com/install-anydesk-raspberry-pi/ ).
Can't really say what the problem is with the Anydesk version from the official website, just googled enough until I found a solution.
Edit: there is also something along the lines of Anydesk being not supported on 64bit, and a workaround: Anydesk not installing in Raspberry Pi 4 with Raspberry OS 64 bit
