macOS EACCES: permission denied, open '/var/folders/...'

"electron-builder": "^23.3.3",

node v18.15.0

"electron": "^25.9.8",

macOS

During the building process the electron-builder exits with an error 'EACCES: permission denied', so eventually it cannot create a temp folder but there weren't any changes in build scripts and it just started occurring. Logs:

Did something change with your OS/node versions or CI runner? Seems odd that a system-related issue would appear without changing the electron-builder version either

No, there were no significant changes in code or environment like you mentioned. I have tried to use a custom tmp folder location but it didn't help, the error remained the same. Other than that I ran the build with a more detailed build logs but it didn't give more context about the error. Is there any documentation which mentions in which cases the tmp folder could be used?
