A workaround is to:
1. Open `Account Settings` in your browser (`Open My Vault` → `Account Settings`)
2. Press `Show Advanced Settings`3. Set `General → Security → Password Iterations` to *exactly*`100100`
LastPass will ask for your Master password and re-encrypt your vault. After that using `lpass`*should* work again.
It helped me, hopefully it will help you (and others) too
