Target MS Word file crashes after a few minutes, copying into new Word Doc ou source file not working this time (Studio 2019)

Hi

After creating the translation file from Studio 2019 into MS Word, the file crashes after a few minutes. It happened before, and copying the file into a new Word doc worked last time, but not this time. I have also tried to follow a solution given here last year and I copied my file into the zip source archive (just dragged it into the folder, don't know if it was correct), or I copied the target file into the source file. Nothing works this time and the doc crashes (it's 143 pages with Excel docs embedded and images).
