Default "Unable to find an Audio Interface..." - fine after computer restart.

Apologies for the lack of detail here. I helped move a studio across from using Focusrite converters to Avid ones. Everything working fine, but after powering down and then restarting the next day, the first launch of Pro Tools gives the "Unable to find an Audio Interface on first HDX card" error. Restart the computer and boot Pro Tools again, and it works fine.

The HDX card is in a Thunderbolt 3 chassis, and the converters are 2x HD IO and a 8x8x8. Loop sync is setup correctly, and all the cables have been reseated.

Anyone seen this before? I know it's not fatal, but I'm just trying to make it as smooth as possible and hopefully minimise frantic support calls to myself

I'm waiting for details from the studio about chassis model, PT version etc. I'm pretty sure PT is 2020 but not the latest update.

Thanks all
