*If you are attempting to leave BIAB running but minimized while opening RealTracks, then that is your problem.

Shut down BIAB before starting Realtracks.

Because they will start a catfight for your MIDI and Audio resources. They use the same engines under the hood.

If you MUST run both at once, try using MME sound drivers on at least one of them if not both. ASIO can be a "one man dog" driver.

Use of the VSC DXi can also sometimes be problematic, although I have found that it can actually start two different instances when selected as default synth in the two programs at once. This too, can sometimes get problematic, but will often work, just don't be surprised if all of a sudden the VSC DXi synth being used by one program starts receiving commands from the other program or the like.
