After upgrading to the latest version of OpenCode, it won't respond/open. Help!!

Question

I just updated to the latest version of OpenCode（v1.1.53），my os is win10, but now it won't launch. Clicking the icon does nothing, and there's no output when running the command in PowerShell or CMD. Any help would be appreciated!

This issue might be a duplicate of existing issues. Please check:

opencode command cli cannot be started #11236: opencode command cli cannot be started (Windows PowerShell, similar upgrade issue with no response)
Everything goes blank on launching -Update #11322: Everything goes blank on launching -Update (Windows 11, blank screen after launch)
Windows Defender reports Trojan:Win32/Wacatac.H!ml when launching the latest version of OpenCode #7919: Windows Defender reports Trojan when launching OpenCode (Windows security issue preventing launch)
Opencode will not launch if you set Agent permissions as True/False instead of Allow/Deny #7810: Opencode will not launch if you set Agent permissions as True/False (Windows, won't launch after upgrade)
Opencode become stuck all of a sudden. Does not launch anymore. #5485: Opencode become stuck all of a sudden. Does not launch anymore (Windows, launch issue with blank screen)

Feel free to ignore if none of these address your specific case.

D:\op-test>opencode run hello --print-logs

D:\op-test>
no response

Me too.

Please rollback the opencode to the old version 1.1.51. It works again now.

Title: OpenCode crashes with STATUS_ILLEGAL_INSTRUCTION on older Intel CPUs (pre-Haswell)

Description:

OpenCode fails to run on systems with older Intel processors (Ivy Bridge and earlier) due to the use of CPU instructions not supported by these processors. The application crashes immediately without any error message or output.

Environment:
• OS: Windows 11 (Build 22631)
• CPU: Intel Core (Ivy Bridge, Family 6 Model 58) - 3rd Generation
• Architecture: x64 (AMD64)
• Shell: PowerShell 7.5.4
• OpenCode Version: v1.1.53 (affected), v1.1.30 (works)

Steps to Reproduce:

Install OpenCode v1.1.53 on a system with an Intel Ivy Bridge (or older) processor
Run opencode --version or opencode
The application exits immediately with no output

Expected Behavior:
OpenCode should start normally or display a clear error message about CPU compatibility.

Actual Behavior:
The application crashes silently. When run from terminal, it returns exit code -1073741795 (0xC000007D = STATUS_INVALID_IMAGE_FORMAT) or -1073741510.

Windows Event Log Analysis:
Root Cause:
The exception code 0xc000001d (STATUS_ILLEGAL_INSTRUCTION) indicates that the binary contains CPU instructions not supported by the processor. This is likely due to the binary being compiled with AVX2 or other instruction set extensions introduced in Intel Haswell (4th gen, 2013) or later.

Workaround:
Downgrading to version v1.1.30 resolves the issue. This suggests that newer versions introduced compiler optimizations targeting modern CPUs.

Version Bisect:
• v1.1.30: ✅ Works
• v1.1.53: ❌ Crashes

Suggested Fix:
Consider one of the following approaches:

Compile release binaries with a baseline x86-64 instruction set (SSE2/SSE3) without AVX2
Provide separate binaries for legacy CPUs (e.g., opencode-windows-x64-legacy.zip)
Use runtime CPU feature detection to provide a meaningful error message

Additional Context:
• The binary is correctly identified as x64 PE format
• Visual C++ Redistributable 14.44 is installed
• WebView2 Runtime 144.0.3719.115 is installed
• The issue affects Scoop installations as well as direct downloads from GitHub releases

npm install -g [email protected]，after install ,its version is 1.1.51,but after run opencode,exit,version auto upgrade to 1.1.53,run opencode no response again.

I am using Ubuntu 20.04.6 LTS. Opencode was running properly on version 1.1.51, but after upgrading to version 1.1.52 or 1.1.53, it no longer runs.

npm install -g [email protected]，after install ,its version is 1.1.51,but after run opencode,exit,version auto upgrade to 1.1.53,run opencode no response again.

please edit the opencode.json in the folder ~/.config/opencode, insert the setting "autoupdate": false,, then it will not update again.

@Afonsojr

@Afonsojr @BassemN @Casperlet @freewinder-tech can you upgrade to latest (1.1.64) and let me know if this is resolved?

@adamdotdevin

@adamdotdevin Unfortunately, in my case, the issue is still there even in version 1.1.63.

sorry, 1.1.64 any better?

not work even 1.1.64

@adamdotdevin

@adamdotdevin Good news! I can now access Opencode via the terminal after updating to version 1.1.65

@Casperlet

@Casperlet, it worked for me after updating to version 1.1.65. Try updating like I did and see if it resolves the issue.

@BassemN

@BassemN yes, the 1.1.65 works, thanks.

Confirming 1.1.65 fixes it. Nice work!

v1.1.30 works with i7-4770, but not 1.1.65
