When opening Write on another pc the font is messed up

I use Google Drive to transfer docs between my two computers.
Comp 1 is mac laptop whre I wrote the text first. Save to Google Drive an open on Comp 2 (Win 10 pc).
The font is really messed up. There are capital letters on top of the text and they are not the correct letters for that word.
Retyping does not fix it.
Open in Pc1 and it looks normal.

Any ideas?

Both LO are the latest version.

Screenshots don’t tell a lot, you should upload a sample file at a free hosting site like www.mediafire.com, preferably one where you don’t have to register to view a file. We need more information, like: do you save in the native format of Writer (odt) or in Word format (doc or docx). Do you have the font used in creating the file on both computers? There seems to be more wrong than fonts here, but once again, you can’t judge that from a screenshot.
