v31.0.0: genesis.json causes panic in gov.InitGenesis (nil pointer dereference)

[Arbilad]

Bug Description

Cannot start new Osmosis v31.0.0 node - crashes during genesis initialization with nil pointer dereference in gov module.

Environment

• Binary Version: v31.0.0 (commit c1adfd5)
• OS: Ubuntu 24.04 LTS
• Installation Method: Official Osmosis Installer (get.osmosis.zone)
• Genesis File: https://github.com/osmosis-labs/networks/raw/main/osmosis-1/genesis.json

Error

panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x2f9c693]

goroutine 1 [running]: github.com/cosmos/cosmos-sdk/x/gov.InitGenesis(...) github.com/cosmos/cosmos-sdk@v0.50.14/x/gov/genesis.go:21 +0x153

Steps to Reproduce

1. Run official installer: curl -sL https://get.osmosis.zone/install > i.py && python3 i.py
2. Select: node → mainnet → default settings
3. Start service: sudo systemctl start cosmovisor
4. Node crashes immediately with above error

Expected Behavior

Node should initialize from genesis and begin syncing

Actual Behavior

Node crash-loops every ~7 seconds at height 0

Additional Context

• Tested on fresh Hetzner dedicated server (64GB RAM, NVMe)
• Same error occurs with manual setup following docs
• All snapshot providers currently unavailable/broken:
  • snapshots.osmosis.zone: 504 Gateway Timeout
  • quicksync.io: JSON API broken
  • State-sync: RPC timeouts

Cannot sync node by any method due to this genesis.json bug.

Need working genesis.json or alternative sync method for v31.0.0.

Any help will be much appreciated, thanks in advance and Happy New Year !
