Fail to build FMU

[MKarvy]

Hi,

I am trying to create a FMU using your the tool 3.1 in Matlab 2021a. For test purposes I made really simple model from scratch. As an error I get this:

The call to rtwsfcnfmi_make_rtw_hook, during the after_make hook generated the following error:

which is cased by:
Failed to build FMU.

I have no idea why this is. I followed every instruction given by the tool.

Here is the whole report:
