Have you permitted Ubuntu 18.04.1 to upgrade - should now be 18.04.2 (run inxi -S in a terminal to get latest configuration)? But I doubt the problem is any minor revision of Ubuntu, as Impress has been stable on earlier versions of Xubuntu, which use the same core files.
Start OO in a terminal (type openoffice4); allow it to crash, and note the error message from the terminal; this may be helpful in diagnosing the cause.
Apache OpenOffice 4.1.8 on Xubuntu 20.04.1 (mostly 64 bit version) and very infrequently on Win2K/XP
