You got me wrong, I meant that most of these fixes are fixes I already tried and a few others are for java edition, bad wording.
Minecraft Game Crashes and Performance Issues FAQ – Home - Didn't fix anything, as I said, I've got all drivers, especially graphic card ones, updated.
(1) Minecraft Bedrock is crashing on startup on a Windows 10 PC. Uninstalling and reinstalling does no good. : Minecraft (reddit.com) - This is a windows "N" version issue that requires media feature pack installation for the game to work (It's a dependency of the game apparently). I do not (should not?) suffer of this issue being on Windows 10 Pro, I did double check and can't even install that pack anyway since it's apparently included with this version of my system.
How To Fix Minecraft Keeps Crashing On Windows 10 [ Fixed ] (techworm.net) - This page mostly lists super basic "fix" you find everywhere that I already tried many times to no avail and some of the fix listed talk specifically about repairing issues with the JVM which is specifically only relevant for the java edition anyway (my java edition works fine by the way).
Minecraft Keeps Crashing Before It Starts—What to Do (playerassist.com) - Same as the link above, pretty standard fix and some of them specifically targetting the java edition.
Minecraft Bedrock crashes on startup (gamerz-forum.com) - No luck here. I don't run on integrated graphics, I'm on a custom built tower PC I made myself.
(1) Minecraft Keeps Crashing | Crash on Startup on Windows [FIXED] - YouTube - You already linked that one on the very first reply. It overlaps with fixes already discussed in the links above and presents some java repairs (again, irrelevant for bedrock).
Also about point 3) of your reply, I don't have performance issues in any game, and in Minecraft well, I can't really know since I just can't start the game xD
As for your point 4), as I said, drivers are updated and even my BIOS has been flashed to a decently recent version. If there isn't any known conflict with the game and some of my drivers, I would be very surprised the issue lies there, even if everything is possible I guess.
As for point 5) I didn't do it yet as I am using this computer for critical work in the next months at least so I'd rather not go that route yet. I could though find some time in this coming week to try out some things with a different user account on my machine see if it's an account related issue.
Another possible problem source could be some software conflicts but after checking the known conflict from Mojang's list on their website, I did not quite find anything that is apparently known to conflict with the game.
It's quite a crazy issue. I will report back with anything new, it's currently hard for me to spend that much time for such a trivial thing during weeks I have heavy workloads.
Kind regards.
