I tried many of things, but it's a good idea, I remember that a few years ago disable fullscreen logo and set delay on 3sec, I will try to increase delay, thanks
Had a similar problem a while ago. I made a script (batch) that first checks, how many GPUs are in the system ("PhoenixMiner.exe -list > GPUS.TXT"). You then can analyze the GPUS.TXT file how many GPUs are available and compare it to the number of GPUs that should be there. If its okay, then start Phoenix with the normal parameters, otherwise generate a shutdown/restart.
It's just a workaround but it did what I wanted :-) Maybe its a way for you also to get the problem solved. Anyway you should try to find and fix the problem itself...
