Hello,  

It seems you are encountering an issue with loading a project template in SDL Trados Studio 2019. Here are some steps you can follow to resolve this issue:  

**Step 1:** Close SDL Trados Studio if it is currently open.  

**Step 2:** Navigate to the folder where the project template is located. In your case, it is:  

`C:\Users\Home-PC\Documents\Studio 2019\Project Templates\`  

**Step 3:** Check if the file `mmmm.sdltpl` exists in that location. If it does not, you may need to remove the reference to this template in Trados Studio.  

**Step 4:** Open Trados Studio and go to `File > Setup > Project Templates`. Remove the template that is causing the error.  

**Step 5:** Try creating a new project again. If you encounter a new error, repeat the process of removing the problematic template.  

**Step 6:** Once you have resolved the issue, you can re-add your project templates from the correct location in `File > Setup > Project Templates`.  

If the problem persists, consider resetting your user settings by renaming the folder located at:  

`C:\Users\%User Name%\AppData\Local\SDL\Trados Studio\15.0.0.0` to `15.0.0.0_old`. This will reset your settings and may help resolve the issue.
