Toolbox failing when there is a container running on another terminal with different $HOME

This issue arose when I wanted to avoid sharing my home directory for several disposable toolboxes I needed. Since toolbox is just a bash script I created a directory and changed $HOME to that directory after that I was able to create and use toolboxes in that specific directory. After that if I open a new terminal and try to use my old toolboxes they fail. I have created an issue on the toolbox repo repo but since no one understood the behavior I was wandering if any body can explain it to me. Experimenting around I was able to find that the issue was related to volume sharing. It might be a fuse issue since killing all processes related to fuse allows normal behaviour.
