When I minimize the session (using the top right hot corner) and go back, I
can't open the window after the second time I did that (minimize & reopen
the window). The session still seems to be working & valid, just I can't see
the window.

I had a similar issue and debugged it successfully.  The issue occurs
because the x2gostartagent script and the x2goresume-session script become
out-of-sync with respect to options file when fullscreen is used, i.e., the
x2goresume-session expects the geometry field to be in position 13.  The
fact that the geometry field is missing causes x2goresume-session to misread
the options file and subsequently corrupt it.  To resume a fullscreen
session, you may edit the options file to correct the corruption.  To
prevent the issue in new sessions, I edited the x2gostartagent script to
coerce it to include an empty geometry field.  Unfortunately, the post
service required splitting the diff lines but I think you should still be
able follow it.
