simulink library does not show installed tool boxes

My matlab version is 2024a, when I start Simulink, in the library browser, all the toolboxes I installed does not show up, just leave all these blank tabs. If I search for a block that is installed, it will not show in the library browser, however, if I directly type the name of the block in the main interface, it can be added. As you can see in the figures below, I take block 'MVDR' as an example.

And in the Add-ons manager, it shows that the tool boxs 'Phased Array System Toolbox' that contains MVDR block is already installed.

What is wrong with my Simulink? How can I solve this problem?

Hey @zuyuan,

Maybe your MATLAB install's path or toolbox cache got corrupted. You try running the following commands in MATLAB and then open the Library Browser again

>> restoredefaultpath
>> rehash toolboxcache

Then, you can refresh the library browser by pressing right-clicking and selecting "Refresh Library Browser" (or hitting F5 on Windows).

Thank you @Animesh, problem solved!
