Crash when using RTLTMPro

[mjamalil]

Hi I'm getting random crashes since I used your library. First of all thank you for developing this. It's such a nice plugin for supporting Arabic and Farsi in Unity

Thanks for reporting this. There is no indication in the stacktrace that this is caused by RTLTMPro. The stack trace is for saving a prefab scene most likely. The seg fault may or may not be due to a RTLTMPro component in the prefab.

• What versions of Unity / RTLTMPro are you using?
• Can you replicate the issue with a fresh project that uses only RTLTMPro? (No other third party or experimental assets / packages)

[mjamalil]

I'm using unity 2020 and RTLMPro v3.3.2. It's very hard to replicate, it doesn't happen very often. I will try to replicate it in fresh project

[mjamalil]

I should mention that it only happens in Unity editor

[hk1ll3r]

I use Unity 2020.3.13f with RTLTMPro 3.3.2 all the time and haven't had a problem. The only way I could help with tracking down the issue is if you share your project and repro steps (for when is more often happens). My hunch is that a rare combination of prefabs / nested prefabs and RTLTMPRo is causing this.
