Altium error at compilation
The format of the error message is:

Same parameter contains different types &lt;Object&gt; &lt;Types&gt; ,


So the Object in your error message is 1 - MCU.SchDoc

Open up 1 - MCU.SchDoc, right click on the page background (not on a component), select Options, then Document Parameters.

Look through the list of parameters to see if you can find a parameter name duplicated, and delete the one that you don't want or is wrong.
