yes, i don't understand the error

RE: ATTENTION! Pure (unoptimized) backend kernels selected. - pdo - 05-14-2022

Ok, well it's not an error, it's telling you that you're using a "pure" kernel to crack your hash. There are good reasons to use a pure kernel, but it's going to be slower than using an "optimized" kernel. The message then says if you want to use an optimized kernel, you can add "-O" to your command line.

Good luck.

How were you able to get so many optimizers, and what do they do? I'm new to this and just started yesterday because I forgot the password of a .7z file lol

Optimizers will automatically be applied when using the -O parameter. Based on your hash and what details are within your hash it will eliminate/add optimizers to increase the hashrate but also has fallbacks such as password length. This is all done automatically by hashcat and you do not have to apply each one separately.

Use the Command : sudo hashcat -O -m 1000 <hashfile> <password file >
just add "-O" to resolve the error
