I’m on a Mac. After the problem returned for me I launched Activity Monitor and Console which revealed one of the multiprocessing threads was bloating up and hogging RAM. With the system starved of memory I was having aeselflnk crashes, BG renderer connection problems, and the 1610153464 error. Eventually the problem was traced back to an odd bug that a script (Load Project or Template from AEScripts) was causing on my machine if it was setup in a particular way.
Removal of the script fixed the situation.
Perhaps try launching the Activity Monitor, or the Windows equivalent if you are on that platform, to see if one of your multiprocessing threads is going out of control. Maybe it’s a similar issue.
