Incompatibility when moving to dp10

One of my projects - the one I’ve been using to play with and report bugs - hits a major problem with dp10.

I can select / load the project OK, but when I (immediately) switch to “Run” mode, LCCreate freezes with the spinning circle icon, and needs to be "Force Quit"ted.

It’s project “Addresses”, which you (LCLtd) are welcome to look at (if you can). If not - how do I provide it to you if you want to check?
