It might be blocked or in quarantine. Not sure how to handle that on windows. @Hona maybe?

It's an issue of ImDisk RAMDisk, using https://github.com/tmcdos/ramdisk fixed it.

Cool, sounds unrelated to something we should fix. Thanks for updating the issue :)

had the same problem, found a different workaround though.
My %TEMP% was set to the ImDisk RAM drive. If I just set a different TEMP before starting opencode, it works well:
opencode.cmd:

SET "TMP=%LocalAppData%\Temp"
SET "TEMP=%LocalAppData%\Temp"
opencode.exe %*

Could you please let me know how you solved it?
