Is it possible to purge a spreadsheet of a pivotable?

I have a file I'd like to completely remove the pivotable from...I've tried to just delete the pivotable tab but I just get an error and it doesn't go.
That's ultimately the main question.

Aside from that, for some background, this was my first pivotable venture and I built it off of a single spreadsheet with no external source links, but rather multiple tables on the sheet serving as the source links to the main table on which the pivot table sourced from. All was beautiful and I kept expanding the tables with more date and thinking of ways to improve so I made changes and at some point over a few weeks time, suddenly any use of the actual pivotable causes Exel to crash. This is the only file it happens with and only when I mess with the filters on the pivotable. so at this point I want to salvage the original spreadsheet, which if I edit it alone and don't touch the pivotable at all, it seems to save just fine and doesn't cause any crash at all.

But I'd like to redo the pivotable from scratch at this point to see if it was maybe all my tweaking, so I'm wanting to just purge all the pivotable from the file all together so I can start with a whole new pivotable.

Hope this makes sense. I loved the pivotable before these issues started popping up and would really like to be able to make use of it again, but can't while I'm stuck with this original pivotable that seems to have become buggy.

Thanks!

this I Excel for Mac v16 (2016 I believe) and I'm running Mac Mojave 10.14.5

So what is the useful information you would like to see? I'm not an expert, so I don't know. But if you tell me, then I can try to provide the information. The only other thing I can add in response to your reply is that nothing is sourced from anything else. There are multiple tables on the same works sheet and same work book. The pivot table is pulling from all of those tables on the same single work sheer.

Ultimately, I'm trying to remove the pivotable and just leave the original spreadsheet containing is tables. That's it. Is there a way to do that and if so, how please?

Thanks
