MATLAB was unable to start

Windows 10 21H2 VSCode 1.82.2 MATLAB Extension 1.1.3 MATLAB 2022b

Tried restarting/closing VSCode, MATLAB and restarting PC. Tried installing MATLAB in folder without whitespace. Tried MATLAB 2021b and previous versions of MATLAB Extension;

Can you provide the following info:

1. Launch MATLAB separately and run matlabroot. Is the value you have provided in the "Install Path" setting the same as what MATLAB is outputting?
2. Can you confirm that there is no trailing or preceding whitespace in the "Install Path" text field?
3. In VS Code, open the Output tab (Ctrl+Shift+U) and select "MATLAB Language Server" from the dropdown. Please share any errors displayed in this log.

Hello @dklilley,

1. matlabroot returns the same path, as specified in "Install Path" setting
2. Yes, there are no extra whitespaces in "Install Path" setting
3. Here is "MATLAB Language Server" output : (08:58:36) matlabls: Launching MATLAB... [Error - 8:58:36 AM] (08:58:36) matlabls - ERROR: Error launching MATLAB: spawn C:\Program Files\MATLAB\R2022b\bin\matlab ENOENT [Error - 8:58:36 AM] (08:58:36) matlabls - ERROR: Error launching MATLAB: Error [Error - 8:58:36 AM] (08:58:36) matlabls - ERROR: Error launching MATLAB: Error: spawn C:\Program Files\MATLAB\R2022b\bin\matlab ENOENT at ChildProcess._handle.onexit (node:internal/child_process:283:19) at onErrorNT (node:internal/child_process:476:16) at process.processTicksAndRejections (node:internal/process/task_queues:82:21) (08:58:36) matlabls: MATLAB process terminated

Same issue.

Windows 10.0.19045 22H2 VS Code 1.85.1 VS Code MATLAB extension v1.1.5 MATLAB 2023b

Steps taken:

• Restarted VS Code, MATLAB and PC.
• Reinstalled VS Code and MATLAB extension.
• Quadruple checked the MATLAB path in the extension and ensured it was the same as the 'matlabroot' output.

MATLAB Language Server output:

Thanks for reporting this. I have not been able to reproduce this on my machine, but here are a few things to try/check:

1. Is there any leading/trailing whitespace in the installPath setting's text field in VS Code? This probably isn't the issue, but has been known to cause problems.
2. From a system command window, does running the following (including the double quotes) launch MATLAB correctly? "C:\Program Files\MATLAB\R2023b\bin\matlab.exe"
3. Does running matlab from a system command window launch MATLAB? On Windows, the extension will attempt to launch MATLAB with the matlab command if no path is provided in the setting. If this command works on your machine, try clearing the installPath setting.

[M-Moschetti]

I can confirm that there are no leading/trailing white spaces.

Both options 2. and 3. successfully launch MATLAB. Clearing the InstallPath settings changed nothing.

Thanks for your help.

One more quick question - Are you running VS Code from the Windows Subsystem for Linux (WSL)?

[M-Moschetti]

No, I am not.

Same problem in MATLAB-language-server, https://github.com/mathworks/MATLAB-language-server/issues/33. So May cause by MATLAB-language-server ?

[dklilley]

Hi all, If you have a chance, can you try this again with the new release of the extension (v1.2.1) and let us know if you are still encountering this issue?

[M-Moschetti]

I no longer have access to the offending machine, so I cannot test this. My apologies.

@M-Moschetti no worries, thank you for the response!

[dklilley]

I believe this is likely resolved. Closing this issue for now.

[sbom641]

I am experiencing the same problem VS code - 1.91.1 MATLAB - 2023b Matlab Extension for VS Code - v1.2.4 Windows - 11Pro 23H2

This is the only error message I keep getting: (I do not get/see any errros outputed to the OUTPUT tab in VS Code)

Edit 1: Running matlab from the system command window succesfully does launch Matlab

Any help is appreciated.

[dklilley]

Hi @sbom641 , since this issue is closed, can you open a new issue for this? Thanks!
