Am using R2022b prelease version. When I open the IDE and run for the first time no error but if I re-run that's when I get the error message above. So each time I need to restart the IDE before running my script

I am also having this issue. I'm running Matlab R2021b and am compiling the code into a Python package with the R2021b version of Matlab runtime (v9.11).

Hello @Najmudeen Sibaweihi,
I understand that you are currently facing an issue while importing the runtime during the compilation of your code into a Python package.
This issue may be occurring due to the presence of whitespaces in the Windows "%temp%" directory path. Specifically, if there are whitespaces in the Windows username, it can lead to white spaces in the "%temp%" directory path.
To resolve this, it is recommended to ensure that the Windows "%temp%" directory path does not contain any spaces. In your case, it seems that the directory "C:\Program Files" contains a space character.
Changing to a directory without spaces in the path can help resolve this issue.
Kindly refer to the following thread for a possible workaround:
The suggested workaround is to move the MATLAB directories to another folder such as “C:/” that does not contain spaces.
I hope these suggestions help you resolve the issue you are facing.
Best regards
Chetan Verma
