Problem with file preview panel after DO update (13.4.7 Beta)

After today's update , there was a problem with the file preview panel. Image files are handled correctly, but when I select a MS Word file to preview - the program stops responding. After restarting the DO process, the file preview works, but with a lot of resistance, and selecting any of the .doc or .docx files leads to the program crashing again. I also observed that after restarting DO - previewing Word files in Windows File Explorer does not work either. Restarting the computer / system solves the problem for a while.
Previewing Excel or PDF files does not cause a similar problem.
I tried repairing Office 365 - but it had no effect.
Before the DO update, the preview panel worked fine (or at least I did not observe the described problem).
In the evening I can try to install an earlier version of DO and verify the described problem.

Best regards

No problems here with Office 2021.

Nothing has changed recently relating to viewing files so it's unlikely to be the new beta causing the problem.
