ID:209035 Device chain in use

CAUSE: You set up a device chain in a Chain Description File (.cdf). However, the Programmer cannot communicate with the device chain because another application, such as another instance of the Quartus Prime software or a debugger, is currently using the device chain.

ACTION: Make sure the application currently using the device chain is still running. Wait for the application to finish accessing the device chain and then program the device chain.
