@TianjinAI do you use a proxy by chance?

Sorry, don't know what you mean. But the older version, e.g. 1.1.26, was working with no issues.

can you try killing all bun/opencode processes and reinstalling?

I did. I ran these two lines. But let me try it again once I get home.
'Get-Process OpenCode -ErrorAction SilentlyContinue | Stop-Process -Force
Get-Process opencode-cli -ErrorAction SilentlyContinue | Stop-Process -Force'

Now, I got this error: error sending request for url (http://127.0.0.1:38381/path).
Two questions: 1. are you guys going to make a dedicated ARM64 version? 2. it will be better off, if you can set up a customized ChatGPT for opencode troubleshooting. I know Open-Notebook has something like this set up, which is very convenient to users.

After a few uninstalls and installs, it works now! Still, it will be better if you guys can make this product more stable so that users don't have to go through this rollercoaster from time to time!

Two weeks ago, opencode started malfunctioning: it didn't start some times, and when it started, it showed weird random characters in the screen when I moved the mouse.
I didn't update opencode, it happened just after a windows update.
I have a Windows 11 with ARM processor.
I solved it changing the emulion settings (Properties - Compatibility - Change configuration for all the users - Change emulation settings - Hide most recent emulated CPU features.
I tried a lot of things and this solved it. I hope it can help!

@andyzengmath - I downloaded and installed it via .exe file from github repo.
@joelmontoy - thanks! It made the config changes as you described and upgraded to newer version. It seems working now. However, the cli mode still not working.
