Exact same Issue as MCPE-62944 but on Java Edition 1.19.
I am incredibly angry as my 4 Shulker boxes are now deleted from the world and I do not remember what they contain. Now I must cheat to get my Shulker boxes and items back.
When I rejoined my world after the crash, It spawned me in an earlier rejoin area, but all the blocks I mined between then were already mined. Like a player info error of some sort.

Beforehand, might I add that the crash had reset my options.txt file, starting me at the "Tutorial" (press WASD, hotkeys changed, options changed, and reset my Advancements)
Though a crash report is missing, all that was available was a 0kb crash txt; A massive launcher log was made at the point of incidence.
the launcher_log.txt log with a whopping near 1,000,000 (Million) lines, at 253 Mebibytes. contains only the point of error that happened around 4am PST on July 1st.
Since due to the sheer size of the txt file, I have provided a download link through Google Drive.
Here is the link to launcher_log.txt (265 MB)
