The error message "current transaction is aborted, commands ignored until end of transaction block" typically indicates that there is an error in the transaction that is causing it to be rolled back. This could be due to a number of reasons, such as a constraint violation, a missing dependency, or a problem with the data being imported.

Here are a few steps you can take to troubleshoot and resolve this issue:

1. Review the error logs for more information about the cause of the problem. The Odoo log files can usually be found in the "log" directory of your Odoo installation.

2. Check for any missing dependencies or missing or invalid data in the file you are trying to import. Make sure that all required fields are present and filled with valid data.

3. Check if there is any constraints or fields that are causing the problem, maybe you have a unique constraint that is being violated by the data you are trying to import, try to modify your data to fit the constraints.

4. Try importing the data in smaller batches to identify the specific records that are causing the problem.
   
   It is also important to note that importing a large amount of data can cause performance issues, so it is best to import it in smaller chunks, and it's also a good practice to make a backup of the database before importing data.
