I had the same problem but found a solution for this. This is what worked for me…

  1. Set the virtual memory to more than is currently being used. (had 8GB - 16GB, then Changed it to 32GB - 64GB)

  2. open the baseeditor.ini file located in " UE_5.1\Engine\Config\BaseEditor.ini "
    find and edit
    MemoryMinFreeVirtual=
    MemoryMinFreePhysical=
    both to lower but the same numbers, default is 2048 and I set both to 256.
    save file.
    restart the computer… worked for me…
