Hi, everybody. I am running Polyscope 5.11 on UR5e. When I import the URP file via USB and run it, the following information appears:  
Unknown error: valueStack is full, capacity = 1048576, needed Size = 1048682.  
I tried to put urp file on the desktop and got the same information. Reducing the number of lines of script code, rebooting the system, or deleting desktop files has no effect. I want to know how to solve this problem. Thank you for your help.
