Exception in thread "IPC Process Thread

I am using MATLAB R2019b with windows 10 Enterprise 20H2 OS build 19042.1586.

Everytime I tried to edit a plot (2D or 3D), MATLAB becomes unresponsive.

I can minimize and maximize but I even can't close it. The command window is also unresponsive. After some time I receive the following error:

Exception in thread "IPC Process Thread": java.lang.UnsatisfiedLinkError: C:\Users\???????????????????\AppData\Local\Temp\jxbrowser-chromium-43.0.2357.52.5.4.3.1\data\Temp\jxbrowser-common64-a60ded20-f14c-4744-94df-474eb1350234.dll: Can't find dependent libraries

Hi Ameen,

I can understand you are getting the following error:

"Exception in thread "IPC Process Thread": java.lang.UnsatisfiedLinkError"

The issue may be due to incorrect permissions, where MATLAB may not have write/read/access permissions to "%TMP%\jxbrowser-chromium-43.0.2357.52.5.4.3\". Sometimes these issues can occur due to security software such as antivirus on the computer.

A simple solution to this issue can be one of the following:

• Start MATLAB with Administrator privileges, so that MATLAB is able to access the files in the above mentioned directory.
• Change the permissions of the temporary folder "C:\Users\matlabuser\AppData\Local\Temp\jxbrowser-chromium-43.0.2357.52.5.4.3\" so that anyone can access, however, this may be a privacy concern.

I hope this will help resolve the issue.

Regards,

Shivam.
