Mysqld.exe has stopped working in xampp windows. I started my computer while the XAMPP software was running in the background, MySQL will not start!

It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware.
To report this bug, see https://mariadb.com/kb/en/reporting-bugs We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. Server version: 10.1.25-MariaDB key_buffer_size=16777216 read_buffer_size=262144 max_used_connections=0 max_threads=1001 thread_count=0 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 787107 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. Thread pointer: 0x0 Attempting backtrace. You can use the following information to find out where mysqld died.

I've also come across this problem recently when I was trying to install XAMPP to my computer running Windows 10.
If you read the warnings that is given by the program you can see that it return a lot of errors regarding OS. Given "D:\win32-packages\build\src\storage\xtradb\os\os0file.cc" I'm assuming that your computer has several disks hence it's not C: drive.
You should try installing XAMPP on your C:/ drive along with the Windows system. This solved the problem for me, previously I had it on my E: drive and I was not able to run mysql, but Apache worked fine.
2LDR: INSTALL XAMPP to your C:/ drive along with your OS and return with feedback :)
