I have set up a Matlab project in 2021b and had been using it without issue of a couple of weeks. After not touching it for a week, I can no longer open the .prj as Matlab shows the 'Loading project...' window with the circular widget turning but it won't open the project.

I tried removing any non Matlab related products, and removing all non Matlab official entries in the Path, but with the same result.

I also tried the following command: "C:\Program Files\MATLAB\R2021b\bin\matlab.exe" -softwareopengl

Matlab is not frozen, as it is still responsive to resizing windows & clicking on items in the toolbar, but commands can be entered in the Command Window just not processed.

In terms of resources, Matlab is just idling at 0.1% CPU usage and around 1gb of RAM but slowy rising (+5MB/minute).

Hi Callum,

I understand that you are trying to open the MATLAB project file after a long time but encountering the issue as mentioned in the post.

I understand that you tried to remove non-default entries from MATLAB path. I would recommend you to use below commands to achieve the same through MATLAB command window. Note that following commands would restore the MATLAB search path to its default factory-installed state and remove the paths that you have previously added to the MATLAB search path. It is advisable to save a backup copy of the current MATLAB search path before running the commands.

>> rehash toolboxcache

>> restoredefaultpath

Kindly refer to following links to learn more about the commands used earlier and how to save a copy of the current search path

If persists, I would recommend reaching out to the MathWorks Technical Support team using the following link.
