Still assuming you're running macOS Mojave and RMTV beta 2.1.0.
Also assuming the older SQLite library (and I do not recommend updating since macOS uses it as well).
This shouldn't be a problem though - for this reason, the Linux version is intentionally tested with the old library.
Can you provide me with as much info as possible, since I cannot reproduce the issue here on any of my Mac's (granted: they all run 10.15.3 Catalina).
For example:
- the exact steps? (probably trivial, but I just want to make sure)
- are you using ffProbe/ffMPEG (eg. use audio/video details in the filename, and/or update embedded info in the files)?
Next time you get a crash report from Apple:
We don't want to send a report to Apple, so you can close it.
Next open "Console" which can be found in Applications - Utilities (not to be confused with Terminal).
In the Console window, on the left side, you'll see a list of "Reports" and one of the is called "Crash Reports".
Click on "Crash Reports".
On the right side of the window it will list some applications, and theoretically RMTV should be listed there as well.
Select the most top one for RMTV, right click it and select "Reveal in Finder".
The file there is the one I'd need to look at.
You can either attach it here to a post, or if you have privacy concerns email it to webmaster at tweaking4all dot com.
Hopefully I can see something useful in that file.
