Hi,

There could be several reasons why MATLAB 2023b might boot up slower than MATLAB 2018b on your computer. Here are some possible factors:

1. System Compatibility: MATLAB 2023b has different system requirements compared to MATLAB 2018b. If your system is closer to the minimum requirements for the newer version, it might run more slowly.
2. Preferences and Path Cache: MATLAB speeds up startup by caching the path and preferences. If the cache is corrupted or not properly generated for MATLAB 2023b, it could slow down the startup. You can try refreshing the cache by running the "rehash toolboxcache" command and restarting MATLAB.
3. Toolboxes and Add-Ons: If a lot of toolboxes or add-ons are installed in MATLAB 2023b, it may take longer to load all of them during startup.

You can try running MATLAB in "-nodesktop" mode to see if the issue is related to the desktop environment. You can refer to the following answer for more insight:
