The build has encountered too many local fallbacks.

[Gokul V G]

Hi team,

 I have been working on a project that uses Chromium as the base. We have merged Chromium 124 into our project and started the build using the autoNinja command. Despite successfully solving many merging issues, I am currently stuck with a problem, and the error message from the terminal is not providing any clear clues. If anyone can help me understand and resolve this issue, it would be much appreciated.

This is one of the error, i have received many error like this in terminal
