I often call for matlab in Julia for some comparison purposes. Everything goes well in MATLAB 2021B. However, it crashed after I upgraded MATLAB to the new version of 2022b in Windows 11. I have rebuilt the package in Julia. and also set the environment variable MATLAB\_ROOT = “D:\Program Files\MATLAB\R2022b” and registered the comserver. Does anyone encounter the same problem?
