How to reproduce:
1. Create a new Unity project and import the "MySimpleGraph" Script and "New Graph 1" Graph
2. When the scripts are compiled, import the "Graph" script
3. When the scripts are compiled, observe the Console
Expected results: There is "Use the different extension" error that can't be cleared because the compilation error prevents "MySimpleGraph" from being opened
Actual results: There is a clearable error that doesn't appear again unless the scripts are recompiled
Reproducible with: 6000.4.0b7, 6000.5.0a6
Reproducible on: macOS Tahoe 26 (M1)
Not reproducible on: No other environment tested
Note: Due to the error being clearable, it might seem that it is not important, while the conflict in scripts actually makes the Graph created with the first Script unusable
