I understand that after updating to MATLAB R2020b, you've encountered an issue where "mlx" files will not open and the screen turns blank. This problem may have several causes, and one possibility is that the file may have been corrupted during the update if MATLAB was not shut down properly.
Here are some troubleshooting steps you might try to recover your data:
In your Windows temporary folder, look for a file with a name in the format XXXX-XXXX-XXXX-XXXX. You can find the temporary folder by entering
>> tempdir
in the MATLAB Command Window.
The file should have the same size in bytes as the corrupted file and should have been created at about the same time you updated the MATLAB.
If this temp file can be found, copy it to a safe location and rename it to “mydata.mlx”. Then, try opening this new file in MATLAB to see if it works.
Another solution is to use the file comparison and merge tool in MATLAB. First, create a new, empty "mlx" file. Then, go to the "EDITOR" tab in the toolstrip at the top of MATLAB, and in the first column, select "Compare". For the first file, choose the one that won't open, and for the second file, choose the new empty file you created. After clicking "Compare", a comparison window will open. From there, enter "Merge Mode" and click on the icon that appears between the two columns. This icon will have a tooltip that reads "Replace content in the right pane with content in the left pane". This action should transfer all the content to the new "mlx" file. Try opening this merged file.
You might also try running the "mlx" file to see if it executes without any errors. Sometimes, the code might run correctly in the background even if the editor appears blank. If this is the case, updating to the latest MATLAB version could resolve the editor issue.
