Code Completion suggestions are slow to trigger (AI assistant or Copilot)
I was using a Rider 2023 version and after updating to the newest one last week (2025.x) I've noticed quite a bit of delayed triggering of AI code completion suggestions. It used to suggest a lot faster, like just hitting tab on an empty line or typing one or two characters. But now it's more hesitant. I can manually trigger it with ctrl + alt + \ but I wish it would just do that on it's own.
This seems to behave exactly the same for the github copilot plugin or riders own AI Assistant. And since it happened after the IDE upgrade, I strongly suggest that's the culprit. Disabling one or the other didn't change anything either. If I can't solve this I will have to revert to an old rider version.

I've downgraded back to 2023.1.7 and it works like a breeze! I'm back now to my usual update every 6 months and roll back routine. If anyone comes across this and knows how to fix this in 2025 I'd be very grateful!
• File | Invalidate Caches | Invalidate and Restart
• Follow the steps suggested by File | Repair IDE
• Manually re-generate project configuration settings:
1. Back up and remove the .idea folder and .iml file in your project
2. File | New | Project from existing sources to import the current project and rebuild index files.
Meanwhile, we've released 2025.2 version, and some bugs are fixed with the latest version of AI Assistant, please try and see if the issue persists or not.
