Wallacei X runtime shows that the process has exited

When I was conducting Wallacei X multi-objective optimization, after running for a day, a run code box popped up displaying [Process exited, code 0 (0x0000000) 1 can now use Ctrl+D to close this terminal, or press Enter to restart]. What does this mean? Do I want to click on it?
And the time required for each generation of my calculations is increasing, from 2 and a half minutes at the beginning to about 6 minutes now. What is the reason?

The time required for the solution is completely dependent on the complexity of the processes on your GH canvas. The later generations may be individuals that require more time to be calculated.
also. please provide a screenshot of the error.
