when teleporting away from a location or going through a nether portal my item frames either broke and dropped the items but still had a hit box on the chest or when i relog it would delete the item frame and the items in the chest

This happens to me as well, but only when items or mobs fall through my portal. Like Zombie Pigmen and chickens. Doens't happen whenever I go by myself. Happend twice in one session. The item frames break, item drop onto ground, but after a while they "refresh" or something and are placed back on blocks/walls/fences and whatnot. Same version Java 18w44a

One of my players on my snapshot server had a similar situation after transporting a villager though the Nether, once the villager goes through the portal, items in chests within the same chunk as the portal disappeared, also the book on the enchanting table was not rendering anymore for all of us (see the screenshot).
From the player who experienced this issue:
"{color:#dcddde}Transporting the villager into the nether was no problem, it did bug out a lot with getting into a minecart, getting out wasnt hard. As i reached my base portal i moved the villager in the portal with him then we arrived and i started to experience some lag. From this point the freaky stuff happened, i walked out and saw that all my chests were invisible and the signs and the bed, everything else was visible. I relogged and saw that when i logged back in i had rubberbanded back to the portal, and that the villager reloaded into the nether again, i moved him back to the overworld, to find that there were 2 villagers (the same , basically copied) then after capturing both, they seemed to move with different AI but one turned out to be a fake, he disappeared, well after capturing the main villager again. chests and sign stills invisible, i tried removing them (but before i destroyed the blocks) they became visible, when i checked the chests inventory, it was empty, this was for all the chests that reappeared after being "harmed" without being destroyed. it only happened in the same chunk where the portal was, so i assume it is related to the portal. After relogging a few times trying to fix the problem, we restarted the server, this also did not solve the problem, so we gave back my items in creative and moved the portal out of the chunk hoping for the best. {color}"

Since this issue, server's console now spawns a "Keeping entities which already exists with UUID…" warning every time this chunk is loaded.

This might be related to a "mob duplication" bug happening when crossing though a Nether portal from the Nether to the Overworld. Server caught an "entity already tracked" exception once when loading the chunks with the same villager as explained above:
