Hi, I have the problem with the software crashing with this beta-version (1.9.1.952) I can sometimes when I go through the menu > Open get a view of it for a number of seconds but then it crashes with a crash report.
I created this document on APub 1.9.0/Big Sur 11.1 (Mac M1) sent it to a colleague, he edit it, sent it back (crash), worked on his side APub 1.9.0/Big Sur 11.0?. Then he upgraded on his side to Big Sur 11.1 it started to crash. He got it to work by using Menu > Open while none of his versions works for me at all. The beta version does not help at all in my case.
If you want the file and/or crash reports please let me know!
