The issue is version agnostic / the issue will occur on any version above 1.18.19 and below version 1.19.999.

Summary:
The Holiday Resort marketplace button resource pack causes an assertion on release builds.
Impact:
Partners in the treatment group can not launch Minecraft with a release build, impacting the ability to develop content.

Repro Steps:

Install the release version of Minecraft 1.19.51.01_rc0
Launch the game
If the device is in the marketplace button treatment group observe UI assertion
Open the treatment tags file
Remove the line "mc-rp-holidayres"
Re-launch title
Observe there is no assertion
Observe global resources are re-applied
Re launch title
Observe the treatment tag has been re-added and the assertion again occurs

Observed Results:

When a device has the treatment tag "mc-rp-holidayres" causing the RP for the Holiday Resort marketplace button to load an assertion is caused:
Assertion failed: Unrecognized anchor or alignment value: 'top _left' @ UIResolvedDef::getAsAnchorPoint
Expected Results:

Treatment resource packs should not cause assertions preventing the use of release builds.

Notes:
This issue can be worked around by removing the treatment tag via the files once and then entering settings -> lighting debug -> display treatments -> override experimental treatments -> remove holidayres
