PoE 2 - Softlocked in "The Trail of Corruption" quest "Use the Horn of the Vastiri"

Hello,

My character was sounding the horn in the caravan as part of the task "Use the Horn of the Vastiri to clear the sandstorm" in "The Trail of Corruption" quest in Act 2. I had just clicked the in-game prompt to do this, but I got disconnected.

Now the game still requires me to do this, but the action prompt at the front of the caravan doesn't appear anymore, which makes progress impossible.

I've tried dropping the Horn and getting it from Zarka again, but it didn't work. I tried clearing the "Halani Gates" area again to reach the sandstorm area, but it simply repeats a previous part of the questline and doesn't change anything.

+1 some problem

+1 same here

Also crashed while blowing the horn on Cruel and now soft locked on the quest, at the Halani Gates, the sandstorm is clearly here, the clickable prompt is gone and I still have the horn in my inventory. Cannot progress further at this point unfortunately.

I was just able to blow the horn on my bugged character a few minutes ago.
