Description
I also reported this at mathworks/MATLAB-extension-for-vscode#226, but I didn't get a response, and figured it may actually be more relevant here.
Describe the bug
Whenever I open a matlab file, the extension shows the following popup:
And features which depend on a running matlab instance do not work. This is regardless of whether there is already currently a running instance of matlab. The output pane shows:
(11:39:30) matlabls: Log Directory: <...>

The matlab log is:

There is no file named what is shown after "Printing connection data to file:". When I open task manager while pressing the "Connect to MATLAB" button, it shows an instance of the correct version of MATLAB appearing, and then disappearing shortly after (presumably because the language server has killed it when it prints "Shutting down MATLAB session 1"). Unfortunately it doesn't last long enough to follow the steps detailed in this comment. I'm wondering if maybe there is a flag that I can pass to Matlab manually that would let me check the steps listed in this comment?
Useful Information
- OS Version: Windows 10
- VS Code Version: 1.97.2 (not WSL)
- Matlab Version: R2023b/R2024b (Not WSL; Tried both)
I have no startup scripts, and typing matlab into a shell starts it up properly.
