OpenWrt installation problems on TP-Link RE650 v2

Im having problems installing 23.03 on this unit. According to the docs I can do a factory sysupgrade from OEM. But when I try this it never performs a reboot.

Any suggestions...

I have two units, installed without issue - will look up what version I loaded…

Correction - this is for v1: OpenWrt 22.03.2 r19803-9a599fee93
No issues there.

Oh and this problem isn’t confined to just the latest version, I’ve tried all of the 22.03.x series. I have also tried this on the native oem fw versions 1.0.4 and 1.0.5.
