Project gets stuck on "EditorApplication.Update" when trying to open it

Contacted the Unity customer - a (small) bug is present in the projects code :)

Reproduction steps:
1. Open the user’s attached “My project.zip“ project

Expected result: Project opens successfully
Actual result: Project gets stuck on "EditorApplication.Update"

Reproducible with: 2020.3.40f1, 2021.3.11f1, 2022.1.18f1, 2022.2.0b10, 2023.1.0a13

Reproducible with: Windows 10, macOS

Notes:

on macOS project opens successfully, but opening the “SampleScene“ Scene freezes the editor
In the “Editor.log” file there are a lot of “0x00000228c29987b3 (Mono JIT Code) [playerInventory.cs:19] playerInventory:.ctor ()” and “0x00000228c2998c13 (Mono JIT Code) [displayItems.cs:8] displayItems:.ctor ()” messages, so it seems that the Editor gets stuck on these elements
