Changing language in some games bricks the client

By changing your language in-game, multiple users have been reporting being unable to join our game, Nuke Simulator, with the client instantly exiting without any errors or feedback. This happens on mobile and on PC.

One user reported being unable to see or send messages in the Roblox chat, but only when their language was set to something else. They also reported experiencing weird interactions with different UIs in the game sometimes, such as icons being invisible or gone altogether, unable to be interacted with. Once they changed the language to English, everything began to function normally again.

Additionally, a lot of users have reported the client instantly exiting, on mobile and on PC. I was able to reproduce this myself and have no way of reverting this issue (I’m unable to join the game myself now).

Steps to reproduce:

  1. Join Nuke Simulator
  2. Change the language to Chinese (Traditional)
  3. The client will close instantly without any feedback, crash logs, etc, and the log file looks like it just ends

Other games do not appear to be having this issue as far as I can tell, but I’ve only tried a handful of games that don’t really match the scale of Nuke Simulator. Additionally, this issue began being reported on June 10th. It was also reported on June 11th twice, and today, June 13th.

I will ask users if I can provide their videos of the issue here.

OS: Windows 11 (64 bit)
RAM: 16 GB
CPU: AMD Ryzen 5 5600G
GPU: AMD RX 570 4 GB

Expected behavior

The language in-game should be changed, and the client should not crash.

Hi @Hexcede , thanks for the report! I’m assuming you have RtlTextSupport enabled in the StarterGuiService in your experience. If so, turning it off should be able to avoid the crash for now. We are working on investigating the issue and will let you know when it’s fixed. Sorry for the inconvenience.

Thank you! I appreciate it. For some reason it didn’t cross my mind that that might’ve been related to the issue, we recently turned it on, and I kind of just forgot about it almost immediately afterwards.

Hi @Hexcede , there is a recent update where the fix is turned on. Please verify on your end the crash does not happen anymore when you turn on RtlTextSupport again. We recommend turn it on again and have it verified because RtlTextSupport will eventually be turned on by default soon and it would always be better to discover potential issues when we are still able to toggle it off. Thank you!
