A few things happened the very instant Lex entered through the portal, instantly arriving in Arch-Heaven. First, his Heavens Favor became palpable, as if he was radiating a warm and welcoming aura, soothing his surroundings.
It was as if the aura was communicating with the realm itself, telling it that Lex was a favored one, and was welcome to these lands.
Second, Lex felt his power weaken. If, ordinarily, Lex could demonstrate 100% of his power, then now he was suppressed to around 1%. But measuring it in terms of percentage was not accurate, for even 1% of Lex's power was tremendous, and yet here, he suddenly lost the ability to fly, causing him to fall through the air as he exited the portal.
The Bathroom Slippers did not seem to block any harmful environmental damage, so the suppression of power clearly wasn't due to that. Lex tried a number of ways to stop himself from falling, yet the suppression of power extended to everything he used as well.
