Hi,

It looks like MATLAB is having trouble starting due to an issue with the vendor daemon in LMTools. This can happen if the FlexNet License Manager is outdated, misconfigured, or if there’s a mismatch in the license file. You can try the following approaches to resolve the issue:

1. Ensure you have the latest version of the FlexNet License Manager installed. To check the version, follow the following steps:

• Open LMTools and go to Help > About to check the version. If it's outdated, update it to the latest version.
• In the Config Services tab, make sure that the paths for "lmgrd" and "license.dat" are correct, and the DAEMON line in "license.dat" points to the latest "MLM.exe" file.
• On Linux/macOS, navigate to "/usr/local/MATLAB/R20XXx/etc" or "/Applications/MATLAB_R20XXx/etc", then run the "lmver" command to check that you're using the latest license manager binaries.

2. Verify that the Host ID of the license server matches the "license.dat" and "network.lic" files.
