Error:duplicate 'row.names' are not allowed

[BayanAhmad95]

I gathered data from various sources, but it contained several inaccuracies. After validating and correcting the data, I saved it in the Bibliometrix format. However, when attempting to upload the file, I encountered an error.
duplicate 'row.names' are not allowed

Same issue but in an operation on R console with thematicEvolution. Any answer to this issue? Thanks in advance!

Operative System: Windows 10
R Version 4.4.1
Bibliometrix Version: 4.3.0

I have used the function convert2df firstly and after that mergeDbSources, and then gives me that error. I have also tried with mergeDbSources instead of bind_rows and also gives me an error.

Thanks!
