I had the same problem with update 1.0.43. But fortunately I was able to return to version 1.0.42.
Today I have updated to version 1.0.44 and I have a serious problem with the creation of bullet and numbered lists. Every time I try to create such a list, it appears only the word "undefined" and it is impossible to do anything else within that paragraph.
It would be fine to have the possibility to download again previous versions of the software. Now, I can't continue my work until you fix such bug.
