The issue shows a LevelDB build failure in a CI run, with an error about being unable to open an output file. The linked GitHub issue suggests a known problem. Start by examining the build script in the repository, likely in the src directory, that extracts and compiles leveldb-1.20.tar.gz. Check if the directory 'out-shared/db' exists before compilation, and consider retrying or upgrading the LevelDB version as mentioned. Verify the fix by running the CI workflow locally or in a clean environment.
