Closing Lotus Issue ticket.

I noticed that you running on .dirty version.
lotus version 1.13.2-rc4+mainnet+git.e05fdf892.dirty

I will suggest that build Lotus again:
https://github.com/filecoin-project/lotus/releases/tag/v1.13.2-rc4

Build with CUDA:

cd lotus/
git pull
git checkout v1.13.2-rc4
git submodule update
RUSTFLAGS="-C target-cpu=native -g" FFI_BUILD_FROM_SOURCE=1 FFI_USE_CUDA=1 make clean all
sudo make install

Build with OpenCL:

cd lotus/
git pull
git checkout v1.13.2-rc4
git submodule update
RUSTFLAGS="-C target-cpu=native -g" FFI_BUILD_FROM_SOURCE=1 make clean all
sudo make install

Solution:

1. Delete chain folder in your .lotus path
2. Download snaphot like this: wget https://fil-chain-snapshots-fallback.s3.amazonaws.com/mainnet/minimal_finality_stateroots_latest.car
3. lotus daemon --import-snapshot <filefromstep1> --halt-after-import
4. Wait until import is complete, you will know when process has ended.
5. Start up again with lotus daemon

This solution was without verification, and it should be fine!
But if you want to do it with verification follow the same steps from our Docs:
https://lotus.filecoin.io/docs/set-up/chain-management/#restoring-a-custom-snapshot
just with verification.

I reproduced the issue myself and it worked fine here.
If the issue still persist - comment, and we will continue to troubleshoot.
