I'm also not sure it's intentional or not, because the changelog didn't mentioned this change at all.

Can confirm, before 1.18.10 blocks above 1x1x1 boundary was handled as a warning and worked fine, right now they're broken and shows in Creator logs as error.

I've uploaded my pack which is affected by this and screenshots from game.

I also can confirm that issue. 

This bug is quite annoying, because it defeats whole purpose of Actor Properties as alternative of variant, mark_variant and skin_id components.

Also, properties are not refreshing for players who join for the first time with particular RP (for example: after re-downloading buffered pack). Instead, it throws constant stream of Molang errors. In that case, rejoining or using workaround provided by OP fixes this issue

I also have same issue - I've uploaded image comparison of my pack - on the left there's a image from local world, on the right side  there's screenshot from server - both using the same pack and being played on the same device. (This bug is still case in version 1.17.41)
