cannot delete a sheet on calc spreadsheets

I have a spreadsheet with 8 sheet. One of these, the last is a blank sheet that was used for a while and then finished with. I want to delete it but whenever I try LO goes into melt down and freezes. I have to kill it manually with the ‘X’ out and select force quit. The sheet reloads next time and then has to do a recovery. Is there another way to get rid of this excess sheet? As an afterthought this speadsheet is saved in xlsx format but the same happens in ods.

Could you make a copy of your spreadsheet, for debugging purposes. Remove all sensitive data from it, and if the bug still exists in this version, perhaps try uploading it here?
