No idea if this is related but the last few times I've updated, the app has crashed less than a minute into the first use - it just exits with no warning. I can restart it straightaway and then it's usually fine after that, the exception being when I updated one of the tablets from 3.8.1 to 3.8.9 a couple of days ago and it crashed twice rather than just the once, both within a minute or so. I used it for a couple of hours after that with no problems. This is on an Onyx Boox Max 3. I have 3 of them left to update so I'll let you know if the same thing happens. Not particularly worried about it because it only seems to happen immediately after updating and it doesn't always happen but let me know if I should check whether crash reporting is on or whatever.
