What issue do you have?

2nd computer Joplin failed to decrypt these items multiple times, possibly because they are corrupted or too large. These items will remain on the device but Joplin will no longer attempt to decrypt them.

Maybe starting over would solve this, follow the guide: How to fix synchronisation issues and start over
