This error is caused by a leftover tensorflow_text issue from a previous version's internal dependencies. After upgrading to v4.05/v4.06, the transformers library version change can leave behind incompatible cache files that trigger this BACKENDS_MAPPING error.

Solution:

Completely shut down pyVideoTrans (ensure no sp.exe process is running).
Delete the _internal folder located inside your pyVideoTrans root directory (D:/PyVideoTrans/_internal).
Download the latest full package (2.7GB) from the official page and extract it overwriting the existing installation (the same D:/PyVideoTrans folder).
Do not apply any patch/update pack on top – use the full package directly.

After doing this, launch sp.exe again. The error should be gone.

If the problem persists, please provide the newly generated logs/YYYYMMDD.log file.
