MATLAB R2024b takes over a minute to startup.
The timing logs indicate that most of the startup time is spent in the "Session Initialize" stage:

Items shown account for 105.7% of total startup time
There is little difference in timing logs when launching MATLAB with no desktop, or between cold and warm startups.
How can I reduce the startup time?
