Description

**Describe the bug**
In a normal conversation with likely more than 50 turns, DeepSeek switches to Chinese after a query with DeepThink turned on.

**To Reproduce**
_Option A (related to bug description):_
1. Start a normal conversation (Instant mode).
2. Make the conversation long (maybe around 60-70+ turns).
3. Use DeepThink in your next query.

_Option B (quicker, but not related to bug description):_
1. Start a normal conversation (Instant mode)
2. Type a long query with DeepThink mode toggled on.
3. Keep repeating 1 and 2 if you didn’t get a Chinese response.

**Expected behavior**
DeepSeek could have responded in the language I was using, which was English. Instead, it used Chinese.
