Touchbar flashing and not working after sleep

My Macbook Pro 13" (2019 - 4 thunderbolt 3 ports) - When I leave my Macbook idle for about 10 minutes and try to turn it back on, the touchbar would give out a white flash and stops working completely. Restarting the Macbook doesn't bring the Touchbar back on. Only resetting the SMC would make it work again. The Macbook would also restart itself with and error message once it restarts. This happens only when I leave it idle for a while and doesn't happen when I'm working on it.

Here are some of the things that I have tried but nothing worked so far:

Quit Touchbar and Control strip from Monitor app.
Kill Touchbar using terminal
MacOS update (currently on Ventura)
Reset SMC and NVRAM/PRAM
Run Disk Utility (including First Aid)
Updated all my apps
Reinstalling MacOS
Creating another User Account (problem still there when using the other User Account)
Deleting Cache files from Library/Caches
Deleting apple.touchbar.agent.plist

Could someone please help???

The thing is if it's a hardware issue, why does it turn back on after SMC reset? I went to the Apple store once before (for a fan overheating issue that time) and they told me it's because sometimes when you migrate your data from a different Macbook (in my case, I had a Macbook Air before this one), the software might not be compatible. I was shocked by this answer but never got the problem resolved back then. And that was when I got the Macbook for only a few weeks!!! I managed sort that issue out myself by reinstalling MacOS. Now I'm out of warranty and I do not wish to spend over €600 for the service if I know they are just going to do some minor adjustments.
