I think your wallet cache was corrupted. Try this

Delete or move wallet cache (the file without .keys or address.txt suffix)
Open wallet in monero-cli-wallet
The wallet cache restores.
After this you should be able to open it in GUI again. Restoring wallet cache in GUI doesn't work yet, therefore you need to open it in cli wallet. You could also restore from seed of course.
