Steps to Reproduce

1. Open Opentoonz, open scene regularly
2. right click on column on xsheet and choose to create new level
3. Choose 'toonz vector level'
4. click either 'ok' or 'apply' it will crash either way

What did you expect to happen?

i thought it would create a vector level and work regularly instead
