Nether Portal not transferring between dimensions

Bedrock 1.19.83 Realms

(Realms+ account with 10+ owner online capable)

     I did attempt to find a paired/related bug, via the search, to no avail. All seem to be a varying bug, not related, or closed tracking from lack of response.

     Approximately 25 players have joined over the course of 3 months. Only happens to one specific person and yet to recreate successfully with another user. We've ran a realm for over 3 years, with several worlds, and well over 100 people in total over the years. First time experiencing this exact issue with any player. Though we have experienced the crashes, the rollbacks, & stuck loading screens with other members, including myself, related to nether portals. Though none from this world aside from this. This user has only been on the realm for 5 days total. I have seen the issue first hand myself via a screen share on our discord server. Another moderator, in game, has also witnessed. And of course the specific user accounts for such on multiple other occasions as well.

     This happens whether the user plays solo or other members online. No active redstone farms/contraptions in loaded chunk where the issue seems to have initiated, or further attempts at other locations. The user experiences this issue in both the nether & the overworld. At multiple portal locations, not restricted to one or a linked pair that has utilized the appropriate survival game mechanics to create. Portals do link correctly & and at the appropriate coordinates. No other user experiences this using the same portals the user has had issues with. The portals do remain lit. User is not riding an entity, nor is an entity riding the user. Not has such happened in the immediate prior several minutes either. When attempting to travel dimensions via the nether portal, the portal remains lit and the user steps in. Nothing happens, no matter the time spent standing in the lit portal. No animation occurs & no transfer between dimensions is initiated. 

     The user plays on a PC with windows 10. Current updated & official MC version. All of our other users use varying platforms, including PC with windows 10 and have had no issues. The user has also never experienced this before. This issue has happened on multiple occasions over the course of his stay (5 days).

     We have resolved the issue, though it does return for this user. User has closed and relaunched game, sometimes corrects, sometimes does not. We have also tp'd the user into the opposing dimension, to which that also fixes the issue temporarily, though returns.

     We do have a ticking area for a one person sleep command system that checks if a user is standing on the bed at nighttime. A lit redstone lamp is queried and if to be found on, the system checks for users on any bed, it then proceeds to add time until redstone lamp becomes unlit. Weather is then cleared, insomnia is then turned off, and back on. System complete. We do also have a death counter system command system that adds total deaths per user, via a score, and displays it using "list" which shows in the pause menu where online players are viewable. We have used these systems in the past with no reference to occuring prior related issues.
