sia is not starting after a power failure when resizing a folder

[esaumell]

sia is not starting. When I use siac -a localhost:10801 host I get:
Could not fetch host settings: [failed to get reader response; GET request failed; Get "http://localhost:10801/host": dial tcp 127.0.0.1:10801: connect: connection refused]

This happened after a power failure while resizing a folder with
siac host folder resize

To see whats going on the siad logs:
sudo tail -n 50 /root/.HandyHost/siaData/siad-output.log

siad v1.5.7

Since I could find nothing about WAL, walFile, metadata or mismatch on github issues I asked on Sia Discord.
There, someone pointed me that contractmanager.wal was corrupted. I just renamed it and siad it's up again.
