It wouldn't surprise me if it's something like that. Tubeless is unfortunately still a little bit of a crapshoot. It works fine the vast majority of the time, but there are still occasional issues with certain combinations.
Especially in a case like this where the tire is being run at a fairly high pressure per its width, it's not necessarily a bad idea to leave a new setup overnight at significantly beyond its actual riding pressures to try to rule out high-pressure-induced blow-off before use.
