Error at Matlab start up

Hi,

I am getting the following error when I start up Matlab. I am using Matlab R2022a.

restoredefaultpath which brings back some functionality.

I have tried to reinstall and directly copying in a working toolbox but this error still comes up.

Thanks!

How did those get there? Did you add the path with the SetPath button on the Home tab, or did you add the path or try to use cd in your startup.m file?

In the command window, what does this show

isfolder('C:\Program Files\Simpack-2020x.2\partners\mathworks\simat')
isfolder('C:\Program Files\MATLAB\R2022a\toolbox\matlab\codeanalysis\analysis')
isfolder('C:\Program Files\MATLAB\R2022a\toolbox\simulink\dee')

The install was normal.

I get 0s for all 3 commands.

I have not set the paths.

I recommend a clean reinstall, and then also remove any path-modifying operations from your startup.m file, if you have one.
