Do you use the version from Humble Bundle with the content package or the version from this page ?
I would suggest to:
- delete the Userfile_* files in the rpg tools folder
- create a new project(keep the template folder and pick an empty folder for your new project)
About the crash dump : Could you please send it to Martin_Mais@web.de ? Thanks!
If you want you could join the Rpg Tools discord for easier communication : https://discord.gg/2hNzhjbb
