Hey thanks, I've used that guide to set up in the past. I've been isolating through Sandboxie for some time now. The problem seemed to happen overnight (11/22). I'm looking into windows settings for a fix, but I haven't gotten far. It seems to be a very strange issue, and I find myself running in circles. I attached a picture that shows the crash happening. Like I said, OSbot can run fine without using Sandboxie in Stealth and Mirror Mode. When I try to isolate with Sandboxie, the problem seems to happen. Any info helps !
