Universal dot screen PCB design

Overview

Physical display, principle explanation, and illuminated examples: Where did the video go? _bilibili_
Some of the screens on bilibili have non-integer screen spacing of 0.1mm, so they are temporarily unavailable. The current board is already 10*10cm.
The reason for designing this board: I often pick up junk screens and must light them up for verification. Using DuPont wires is laborious and unstable, so I designed this board.
The PCB of this board has 4 layers, and there are many components and vias, so The standard version of Lichuang EDA is a bit unbearable, and it would be better to use the professional version.
The current design is very intensive in order to be compatible with the 16-bit parallel port. There is no way around this. In fact, it is enough to be compatible with the 8-bit parallel port.
The main control is STC8 series. Generally, STC8H1K17-TSSOP20 is sufficient for the screen.
If it is a 16-bit parallel port, use STC8H1K28-LQFP32

Could you please advise what is wrong with this circuit?
The circuit below is placed behind the 5V output for voltage regulation, why does Q1 always burn out? Where is the problem in the circuit?
I'd like to ask, is there anyone who has experience dealing with real-time OS, timeout handling, and ICE?
1. What should be paid special attention to when programming on a real-time OS? 2. What should be paid special attention to when dealing with timeouts and time hangs? 3. What should be paid special at
