Hello again, sorry for the late reply.
I have tried out the fix following the steps, which didn't seem to work, I then looked to see the other set of possible fixes below (the ones in red), and followed the 'Avoid using streaming services at the same time.' point.
After disabling streaming services and tabs on my Chrome, the TMP client seems to be running without issue, which is leading me to believe that this is the fix.
If it does turn out to be the fix, great! If not I will be sure to try out the other points too.
Thank you for your help.
