Client crash on scene transitions – Unity Netcode snapshot ReadDelta RemoveAt

[grave folio]

Build: v0.5.11.18+cl40881
OS: Windows 11 Pro
GPU: RTX 4090 (32.0.15.8157)
Repro: Always, 4-player session → crash only on my client during/after scene change (Lobby → Driftspace → Planet). Other players fine but can’t replace 4th slot.

Logs:

Exception when processing snapshot Update command!
System.ArgumentOutOfRangeException: ReadDelta RemoveAt index 0 … Count is 0

and repeated warnings:

must be instantiated using ScriptableObject.CreateInstance instead of new …

Notes:

No AppHangB1, AppCrash, nvlddmkm, or display-driver errors in Windows Event Log.

D3D11 init normal, GPU stable.

Seems tied to corrupted/inconsistent persistent data or MessagePack deserialization (ScriptableObject issue).

Happens only on my profile since v0.5.11.18.

Already tried:
Steam “Verify integrity”
Disabled Steam/Discord/GeForce overlays
Cleared NVIDIA shader caches (some files locked)
No system/GPU errors found
Plan to wipe %AppData%\LocalLow\Keepsake\Jump Space and disable Steam Cloud

Ask:
Is ReadDelta RemoveAt … Count is 0 a known Netcode issue? Could broken user data trigger invalid snapshot deltas? Any way to fully reset the local profile or enable verbose Netcode logs?

Attachments: Player.log + Jump Space*.log_

Update: I just finished a full session without any crash after launching the game with the Steam launch option -force-d3d11.
Looks like forcing DirectX 11 completely fixes the issue on my system — no more ReadDelta RemoveAt index 0 errors and no disconnections, just a normal “ServerNotResponding” exit at the end.
