There is a workaround, posted by rdtt7n0q:
PSA: You can work-around the Valorie animation freeze until it gets fixed, by editing the `www\data\Map120.json` file. If the `"skippable"` value of the broken action is changed to `true` from `false` and you press space, it will skip over after the "sacrifice". The file is hard to navigate because it is not meant to be edited by hand. There are 300+ skippable values in it, you want to change the one a little after the text `I promise I'll catch up soon.`.
