buildkit: Get error: content digest sha256: ***: not found when exporting image

Would help check below issue and advise if any update? Thank you.

When exporting image, I found below error

#18 exporting to image
#18 pushing layers 0.1s done
#18 ERROR: content digest sha256:97bac3dab075a8e745a60a2e05e9f678053d6bca7ad1d109867220704b154443: not found

Then I checked the dictionary: ‘~/.local/share/buildkit/runc-native/content/blobs/sha256’ and file 97bac3dab075a8e745a60a2e05e9f678053d6bca7ad1d109867220704b154443 is missing, but could be found in one of the image manifest files. buildkit version:0.9.0, I didn’t config gc in Buildkitd configure file. I suspect there is an issue, which deletes a shared cache record in default gc.
