I tried to use it and faced indeed a JS crash when trying to add a WagtailFormBlock.
It’s because wagtailstreamforms uses a hack to display some text in the StructBlock: it uses InfoBlock, a subclass of CharBlock that doesn’t render an HTML input. This is not in line with what React StreamField expects, because all CharBlocks must render an HTML input.

I tried modifying WagtailFormBlock so that it uses a StaticBlock instead, and it worked:

form_reference = blocks.StaticBlock(
    admin_text=_("This form will be given a unique reference once saved"),
)

So wagtailstreamforms has to do something like that to support wagtail-react-streamfield. The good thing is that it’s backwards compatible with the existing StreamField.

Note that this will show a Form reference label above the block. To work around that, wagtailstreamforms can rewrite its InfoBlock this way:

class InfoBlock(blocks.StaticBlock):
    @property
    def definition(self):
        definition = super().definition
        definition['label'] = None
        return definition

form_reference = blocks.StaticBlock(
    admin_text=_("This form will be given a unique reference once saved"),
)

It will look like this:
