Once MATLAB is launched I get those error and I am not able to write anything in command window or editor. Not able to open file

Hi @Manoj Manoj

If the above references does not resolve your error then, this might be best handled with MathWorks tech support. Could you submit a technical support request?

Feel free to link to this page in the request.

Thanks,

Hello Manoj,

I encountered the same issue with MATLAB version R2022a. Before this problem arose, I installed Zoom (the videotelephony software), which required the installation of the ‘compat-libstdc++’ package. After installing this package, I noticed that MATLAB stopped working.

It is likely that the ‘compat-libstdc++’ package is causing a conflict with MATLAB. I resolved the issue by uninstalling Zoom. I recommend uninstalling any recently installed conflicting software to see if it resolves the problem for you as well.
