That seems to be similar to 'Bug 39447 - Writer crashes at closing a document with footnotes in a single paragraph over two pages'.
The attached 'temp-49_modified.odt' doesn't crash at closing.
My modification:
Inserted a manual page break on page 3 after "xxhöhxwgew dxx xmsayzsyexxx (zxleyzy 1.1.2007, 1.4.1998) sqwd sowsy wqchy awzxseyzew, da qw dew fesygesyellyew waxprxcsqwdqces ewyhalyew." [highlighted yellow].
All footnotes of the former single paragraph are now in a second paragraph on page 4.
