Hi, not sure if this happens to you all but it happens to me quite often which is very frustrating. Almost every time I bind a mesh with bones, the software crashes. So I had to reopen Spine, repeat the same action, program crashes, again and again. It took me extra time to finish binding for one project. I'm using version 3.5.51 Professional. Hopefully this issue can be fixed. Attached is the log and screenshot. Thanks!
