You can use the justice.gov search box to find several different copies of that same email.
The copy linked in the post:

Three more copies:

https://www.justice.gov/epstein/files/DataSet%2010/EFTA02154...

Perhaps having several different versions might make it easier.
Also, I found a different base64 encoding with a different font here:
