I recently installed the game to try out the new changes and I attempted to start my own singleplayer world. Unfortunately, it reached a point where it was "initializing world..." and never finished. I even let it sit for 30 minutes with no changes.
I opened up the console and the last messages to be printed was "Started thread GenerateChunks" and the only thing I could do was close the game.
In my attempts to try and fix this issue, I have tried every branch available on Steam and the only one that had any difference was 1.4 where it would just crash instead of indefinitely loading.
I tried hosting a dedicated server, connecting to other servers, and tried random gen and the other presets and they all had the same problem.
I used the launcher tool to delete all of the data, I deleted the registry data, and I deleted the appdata folder for the game every time, and nothing changed.
I tried verifying the game on Steam multiple times, and nothing changed.
I even updated my Windows 11 from 10.0.22631 to 10.0.26100 with no changes.
Nothing was making any difference, so I decided to dig into the game code myself. Using the "GenerateChunks" string, I found the thread function ChunkProviderGenerateWorld.GenerateChunksThread and added logging to discover m_RegionFileManager was always null thus it never continued. I did some more logging, and tracked down that the Navezgane world uses ChunkProviderGenerateWorldFromRaw. I added some logging into the Init function and saw that the function calcWorldFileCrcs was never called but getFilenameDTM was. The issue was in GCUtils.UnloadAndCollectCo(). When I added logging into that function, the GCUtils.PostUnload task never completes. I actually *removed* that task from the function, and now my game loads perfectly fine.
I had to actually remove the Garbage Collection code from the Assembly-CSharp.dll just to play the game.
I've included a log file from before I made any changes to the game code, a log file from when I added logging to the game code, and then a log file after I had removed the section of code. The last two log files have quite a bit of extra logging from when I was tracking down the issue.

The section of code I modified in GCUtils:
Because this issue generates no errors at all, I don't actually know what object in memory is causing the GC to indefinitely hang.

- Reproduction Steps
- 1. Install game
2. Launch game
3. Attempt to join a server, create a new or start an existing singleplayer save of any kind
4. Watch console until it prints "Started thread GenerateChunks"
5. Observe that the game *never* finishes loading
6. Close game
7. Open Assembly-CSharp.dll in DNSpy and find the method GCUtils.UnloadAndCollectCO
8. Modify the method and remove the PostUnload task, then save the modified dll.
9. Run the game, and try to connect to a server or load a singeplayer save
10. The game finishes loading and is playable

, something has to be different. Do you have exceptions in windows security for the install/save folders?
