# Troubleshooting

- `UNSUPPORTED_PLATFORM`: use Linux x86_64 only.
- `UNSUPPORTED_GPU`: confirm `nvidia-smi` works and Blender reports a CUDA device.
- `RUNTIME_ARCHIVE_MISSING`: retry the immutable FARPY runtime URL or manually obtain the official Blender 4.1.1 Linux x86_64 archive.
- `RUNTIME_ARCHIVE_HASH_MISMATCH`: discard the download and obtain the official runtime archive without modification.
- `RUNTIME_BINARY_HASH_MISMATCH`: extract the verified runtime archive without modifying the Blender binary.
- `APP_ISOLATION_*`: choose a frozen profile supported by the GPUs visible to Blender.
- `RUNTIME_VARIANCE_EXCEEDED`: preserve all evidence; do not rerun selectively or discard passes.
- `NONDETERMINISTIC_OUTPUT`: preserve all output files; do not choose a preferred output.
- `DISCLOSURE_VIOLATION`: remove prohibited optional attribution or rebuild from the original evidence. Do not edit measured values.
