See #544 If it still does not work, assign more RAM: https://stackoverflow.com/questions/1565388/increase-heap-size-in-java

thanks for the quick reply. I've already tried assigning more ram by following this guide: https://helpdeskgeek.com/help-desk/how-to-fix-could-not-create-the-java-virtual-machine-error/#:~:text=The%20most%20common%20cause%20for,to%20launch%20the%20VM%20client. However, he has followed another approach telling java to use more RAM (which in my case didn't resolve the issue), so I'll try the way described in your linked stackoverflow question. cheers

-Xmx512M might not be enough. I always try using my PC's amount of RAM divided by 2. If you have 32 GB, it will surely be slower, but you will surely have enough allocated. Thus, I use -Xmx16G
