Service already installed and running

[IOMAN1]

This error appears when trying to open the application after rebooting the system on Windows. When I investigated this I found "AmneziaWG Manager" service automatically launching on startup, stopping which and setting its startup option to "Manual" fixes the issue and allows me to open the app normally. However, upon opening the app it resets the startup option back to "Automatic", which means I'd have to redo all of the above on every system reboot.
