[{"error":"Error: NON-FATAL: Lock acquisition failed for /Users/posokhinsvyatoslav/.local/share/claude/versions/2.1.117 (expected in multi-process scenarios)\n at fn_ (/$bunfs/root/src/entrypoints/cli.js:2754:2177)\n at H98 (/$bunfs/root/src/entrypoints/cli.js:2754:1257)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-04-22T09:08:58.912Z"}]

TL;DR

The issue might be resolved by checking the lock file acquisition in the /Users/posokhinsvyatoslav/.local/share/claude/versions/2.1.117 directory and ensuring proper multi-process handling.

Guidance

• Investigate the lock acquisition failure by checking the file system permissions and accessibility of the /Users/posokhinsvyatoslav/.local/share/claude/versions/2.1.117 directory.
• Verify if the issue persists when using a different terminal or platform to isolate the problem.
• Check if there are any known issues or updates related to lock acquisition in the version 2.1.117 of the software.
• Consider temporarily removing the lock file (if it exists) to see if it resolves the issue, but be cautious of potential data loss or corruption.

Notes

The provided error message suggests a non-fatal error related to lock acquisition, which might be specific to the multi-process scenario. However, the exact cause of the prompt loss is unclear, and further investigation is needed.

Recommendation

Apply workaround: Temporarily remove the lock file (if it exists) and test if the issue is resolved, as this might help identify if the lock acquisition is the root cause of the problem.
