Matlab not launching but continues to start license activation

I have a new PC and have installed Matlab on this, and run the activation. There are no error messages neither during installation, nor the activation. I have together with our IT support institution checked all tips in this page

Why am I continuously prompted to activate when I try to launch MATLAB? - MATLAB Answers - MATLAB Central

but this did not help. We have also tried to uninstall and re-install Matlab, and have also tried to active computed from the license center and do not know what else to proceed.

Hello @Ingunn Berget,

Please refer the following troubleshooting steps:

• Run as Administrator to do the activation, so that it has permission to write into the correct directory.
• If running as administrator doesn't help, then try to perform a clean installation of MATLAB. Although, you have tried uninstalling and re-installing MATLAB but still it is possible that some temporary and cached folders from previous installations are left which might be used again by fresh installation.
• However, if the issue is still not resolved another step is to uninstall and re-install MathWorks Service Host, because it can also be a cause for startup issues.

Sorry, did this not help.

POint 1. Have tried multiple times

Point 2: As starting from a new PC, the installation should have been clean, but hvae reinstalled a couple of times to be sure. The option with disabling the antivirus program was not feasible

Point3; Did try this, but did not change anything.

I still cannot run matlab - all troubleshootings steps described above and found elsewhere online have been tested.
