I’m encountering an issue running the maxent() function with the dismo package in R Studio. Other parts of my code run successfully, but when running the maxent() function with my data the session gives me a popup that R has experienced a “fatal error” and the session is being aborted.

I’m running maxent() with data that I have successfully ran the function with before. I have also tried it with different, simpler sets of data and am getting the same error. I was initially encountering issues with extremely long processing times, so updated to the latest R Studio and R versions. That issue resolved by now I’m getting the fatal error message and aborted session specifically when running the maxent() function. I also have java and the maxent.jar file downloaded properly in my working directory. The same issue occurred when running the script in R rather than R Studio. Again, I’ve been using dismo and maxent() successfully on this computer for months, but this issue seems to have appeared after updating R and R studio.
