I have a same problem now.
Our environment: MATLAB r2022a and EB Tresos 29.0.0
Different with this post.
1. I try the \NXP_MBDToolbox_S32K3xx\S32K3_Examples\dio\s32k3xx_dio_ebt example not s32k3xx_dio_sc32ct.
2. I had already changed the default work folder for MATLAB add ones by following that (To change the default installation folder, on the Home tab, in the Environment section, select Preferences > MATLAB > Add-Ons), and the path is shorter (D:\MATLAB Add-Ons).

This screen shows installed toolboxes now.
