Seems to be stack related. If you increase the stack size it can handle 500 widgets.
Simpler MRE:
from textual.app import App
from textual.widgets import Label
# import sys
# sys.setrecursionlimit(10**6)
class LabelApp(App[None]):
async def on_mount(self):
for _ in range(500):
await self.mount(Label(";)"))
if __name__ == "__main__":
LabelApp().run()Suggest we try to get a failed stack trace, and seem if we can make it less deep.
I'm also wondering if there is something significant about mounting widgets from the mount handler, which feels like an odd thing to do, but should be possible.
Update: it also only occurs if you await the mounts.

It looks like this was introduced in https://github.com/Textualize/textual/pull/3065/files. Specifically the change from invoke to self._dispatch_message is causing a stack overflow as we recursively bounce between _dispatch_message and flush_next_callbacks.
Fatal Python error: Cannot recover from stack overflow.
