I am trying to look at a link in an email message from alpine. Many (eg
PDF files) work. But Chrome, my browser does not work.

The chrome windows opens on my home machine, but starys blank. On the
remote machine I get error messages

I have gigabit fibre connectivity from the remote machine, so network speed is not a problem.

How do I even start trying to figure out how to resolve the problem?
Which "GPU process"? The last error line occurs about 10 sec after the
first two. There is certainly not enough information there for me to
figure out what is going wrong. (Note, the network connection was NOT
broken so that is one possibility off the table.)

How are you connecting to the remote machine? If ssh, ensure the following are set
# grep X11 /etc/ssh/ssh_config
ForwardX11 yes
# If this option is set to yes then remote X11 clients will have full access
# to the original X11 display. As virtually no X11 client supports the untrusted
ForwardX11Trusted yes

And on the remote system
# grep X11 /etc/ssh/sshd_config
X11Forwarding yes

All of those are yes on both machines.

Also Libreoffice works fine. For example if a mail has a .doc or .docx
file, it will open on my home machine with libreoffice when reading mail with alpine on
the remote machine. So it does not seem to be an X11 problem.

After using ssh to connect to another system on my lan,
chromium-browser /usr/share/doc/HTML/en/common/gpl-license.html
is working ok here.

Are you using chromium-browser or the google chrome?

Google Chrome

on the local machine,
google-chrome-stable-83.0.4103.116-1
on the remote machine.

There is a settings in Chrome/Chromium which allows the browser to use
the GPU directly (Use hardware acceleration when available), as you are
using remote tunneling, you won't be able to use the GPU acceleration
and those you need to disable it on the remote machine before you can
tunnel the window to your machine.
