[6.9.0 beta30] can't access unraid's gui mode

Hi, I'm an unraid user, from China

first sorry for my poor english

i've installed an openwrt vm on unraid and make it handle my home full network(but did'nt use auto start because it always cound'nt apply the option)

if I want to use it i'll start unraid with gui mode and start openwrt and change my monitor output and then play or work

after update version 6.9.0 beta30  the gui mode was disappeared and i can't access it  again, there's only a cursor flash in the monitor and nothing happen

now i'm get the endless loop

if i can't enter gui mode and i can't start openwrt, and other pc(control unraid dashboard) can't access yet, because all of the network gate is create by openwrt

is there anyway to sovle this issue? like change network topology, or change unraid lancher parameter, or some way to start vm with commandline, etc

thanks for your software
