No freeze when opening the file. Placing the cursor tin the first embedded table (Objectifs seance) and pressing the delete row button in the toolbar until the green tables are gone (so page starts with orange heading seance 2)
Comment 3 Telesto 2020-08-15 21:36:03 UTC
Deleting the first row in the table "Objectifs seance" is already enough

sw layout: invalidate margins of body content when moving a fly from page

Before this opening the file and double clicking on a word inside the table froze it. Single clicking and deleting a row worked before this too - so there might have been another relevant fix sometime in 7.5. 
Which is interesting since this bug was bibisected to 


tdf#125685 sw: disregard footnotes in follow table on table split

but the above commit was fixing some fallout from
 b9ef71476fd70bc13f50ebe80390e0730d1b7afb (tdf#134298 sw: layout: remove
left-over page frame without content, 2020-11-13).
