SDLXLIFF Split / Merge throwing error "File Split Failed !"

Hi Community,

Hope everything is going well with you.

We're having issues with splitting a large file with the Split & Merge plugin.

There is an sdlxliff file about 65MB and we would like to split it into several small files for production.
File name: FHR-de-de-Properties.json.sdlxliff(attached)

However, it failed by using 2021 Split & Merge plugin (v3.0.0.4 version) and the following error message displayed:
ERROR: The file is corrupt.

We are using Trados Studio 2021. We tried to split it by word count, equal parts or segment numbers, but all failed.

Do you have any idea of where the error could come from and how to fix it? Was it due to the large file size?

Thank you for your help and all the best.
