            self.data2 = pickle.load(file)

            self.data_buttons = []

            for i in range(len(self.data2)):
                bnum = len(self.data_buttons) + 1
                karrot = self.data2[int(i)]
                karrovt = karrot[0]
                karrovt2 = karrot[1]
                x = karrovt.split("\\")[-1]
                button = Button(f"{i}|{x}|*{karrovt2}s", id=f"button-{bnum}")

    def watch_datavb(self):
        self.update_datavb()

Looking at your code it's not obvious to me what it is you're attempting to do specifically, and I'm struggling to follow some of the code (for example, watch_datavb doesn't seem to be related to anything and, if it was, it contains an infinite loop that's going to tie up your application).

Given that, I'm going to try and infer the more general question and see if I can address that.

It seems to me that you wish to be able to poll some external file and, when the content changes, update the display. As a simple start for this I think I'd be tempted to look at using Textual's set_interval to check in on the file every so often and update the display if something has changed. Or as an alternative I suspect I'd take a look at using something like aiowatcher to react to when the file is changed (I don't know that that will mix well with Textual -- but that's something I'd investigate if I were in your apparent position).

it happen if we try to delete same id twice

[xalteropsx]

  if event.button.id == "del":
            if self.input11.value != '':
                self.delete()
                in_num = int(self.input11.value)
# this work  it work on same id delete multiple since it keep refresh id
                self.query_one(f"#out-{in_num - 1}").update(str(in_num))
#this not work it only delete once then crash after second same id attempt 
                await self.query_one(f"#out-{in_num}").remove()

Unfortunately I'm struggling to properly understand your questions. However, looking at the error message you mention, and the code just above, it looks to me like you're doing a remove on a specific widget in your DOM, with a specific ID. That makes sense, if you want to remove that specific widget with that ID that's what you'd do. What I don't understand is why you'd then want to try and remove it again. The error message you're seeing, and what you're asking and the code you're posting seems to suggest you're trying to remove a widget with a given ID, then remove it again. I don't understand why you'd want to remove something you've already removed.

More generally: would I be correct in thinking that English isn't your first language? That's okay, that's not a problem. But I would ask that you perhaps allow for this as we work through this. What you're asking might not quite make sense to a native English speaker like myself. So if I seem to be asking very basic questions, allow for that: I'm trying really heard to properly understand what it is you're struggling with.

 self.query_one(f"#out-{in_num - 1}").update(str(in_num))

actually this thing refresh the new id after deleting old id

like if i delete something i want my all id to be refresh in order to reperform .remove()
