How to reproduce:
1. Create a new Project
2. Make sure GiCache size in the Preferences is set to 4 GB max size
3. Download cache file from https://drive.google.com/open?id=1Q5IDUH0Xv_Fg6ZjxD8LdfXvgCbE1DQVe
4. Copy the file to the GiCache location (without extracting it)
5. Open the Project and observe the console

Expected Behavior: The Cache is trimmed and no warnings in the Console
Actual Behavior: The Cache is not trimmed and infinite warnings are present in the Console

Reproducible with: 2018.4.28f1, 2021.1.0a4

Workaround: the user should not place unrelated files in the GI Cache.
