How can I prevent the export to create a damaged .zip file? The profile folder has about 50 GB.

For 50Gb I would use a dedicated zip program, Thunderbird export tools appear to tap out long before you get to something like that. That is a LOT of mail.

Microsoft offer the following instructions here

Locate the file or folder that you want to zip. Press and hold (or right-click) the file or folder, select (or point to) Send to, and then select Compressed (zipped) folder. A new zipped folder with the same name is created in the same location. To rename it, press and hold (or right-click) the folder, select Rename, and then type the new name.
