Multiplayer Play Mode package throws file not found IO exception after Small Scale Competitive Multiplayer Template project is created

Steps to reproduce:

1. Create a new Small Scale Competitive Multiplayer template project

1. Check the console after the project is created

Actual results: Errors related to file Not Found IO exception are thrown

Expected results: No errors or warnings are thrown after creating a project

Reproducible with versions: 1.3.3(6000.0.18f1, 6000.0.45f1), 1.4.0(6000.1.0b13, 6000.2.0a8)

Not reproducible with versions: 2022.3.60f1 (Multiplayer Play Mode package is not included in that version of the Template)

Could not test with versions: 2023.2.20f1, 2023.3.0b1 (Small Scale Competitive Multiplayer template is not available), 6000.0.0b11, 6000.0.17f1 (Multiplayer Center package is missing and throws Package Manager related errors on project creation)

Tested on (OS): Ubuntu 22.04, macOS 15.3.2, Windows 11

Notes:

• Errors appear only on Project creation. Trying to clear the library and restart the project did not reproduce the issue
• Errors are clearable. For consistent reproduction - disable all Console clear options
• Error originates from the Multiplayer Play Mode package
• The regression point is likely tied to the inclusion of the Multiplayer Play Mode package to the Template project
  • Marking 1.3.3 as a regression point since it is the oldest MPPM package version included in a template. However, it is possible errors existed in MPPM 1.0.0 and the bug was only highlighted with MPPM inclusion in templates
  • 2023.2.20f1 - 2023.3.0b10 do not have the Template project available
  • 6000.0.0b11 - 6000.0.17f1 couldn't test as project creation fails due to Multiplayer Play Center related package errors
