I tried that and same issue occurs. Please note that this happens on 3 different laptops of mine as well as my desktop. None are over heating and in fact one is liquid cooled and this only started with the launch of 7.0. Several of my friends are complaining of the same issue, as are people all over the steam message boards. I have a small IT company so I have the ability to test it on multiple computers. The ones I've tested it on and can reproduce the exact issue on are the following:

4090 (onboard and dedicated gpus)
4080 (3 of them actually, onboard and dedicated gpus)
3070ti (on board and dedicated GPUs)
3070 (desktop with only a 3070)
3060 (desktop with only a 3060)
2080 Super (onboard and dedicated GPUs)

The all do it with rolled back video drives and fresh installations of Windows with nothing running but XIV. Windows 10 and Windows 11, Pro and Home versions.
