I got a 404 error when trying to get a file from nexus

I am using nexus 3.14.0-04 (helm version).
On October 20, nexus went into read only mode due to lack of heap.
After restarting nexus, a task of the type “repair - rebuild repository browse” was created in Tasks. This task is still in status “Starting” and does not appear to be working properly.
After that, I was able to run the check database, rebuild index, and repair database commands to get/put files from nexus.

On October 24, I got a 404 error when trying to get a file from nexus.
I ran the check database, rebuild index, repair database commands, but no improvement.
After restarting nexus, the “rebuild repository browse tree” task ran and logged that the files in the repository were deleted, as shown below.

I do not think the real file itself was deleted, but I can no longer browse the file from the nexus screen.

I would like to know if you know the cause of this problem and how to solve it.
I am very confused because I can no longer GET the file from nexus.
