This issue might be a duplicate of existing issues. Please check:
Linux x64 (baseline), suggesting the baseline Bun binary is being used, which may point to a CPU compatibility issueIf your CPU lacks certain instruction set extensions (e.g., AVX2), you may be hitting the same class of issue. It may be worth checking whether your VMware VM's CPU configuration exposes the full host CPU instruction set.
