Closed Sony xz1 compact driver problem?

Oke so i finally got araund to do my daily driver sony xz1 compact and when i tried to unlock the bootloader using flashtool also know as sony mobile flasher by androyxde.

I get the following error

ERROR - Cannot invoke “String.split(String)” because the return value of “java.util.Properties.getProperty(String)” is null

now i looked everywhere on the internet literally and i could not find a awnser to my problem but i did find multible people with this problem but no awnser…

but i kept looking and i found that my computer can not find my phone exactlly because when i use command and try adb devices it cant see it but fastboot mode it can.
so i looked for an awnser and said probally need to update your drivers so i downloaded drivers from the sony site installed them then got the message that i have to restart computer before it can go into effect and i do that and then nothing stil does not work i see no adb devices in the list

oh and i selected the allow unknow drivers from the security option in windos 10 so that should be oke

I think this might be the problem that adb devices cant be read seeing as it has to be in that mode when trying to unlock the bootloader in flashtool.

please help because i spent the entire saturday doing this driving me crazy

Edit:this is what it shows in the program

gregory i think i see the problem possiblely

when i put phone in fastboot mode it has seemingly the right driver as i can see it in device manager without a !

so i think that is good

2 having the phone on and it is detected as sony so that is good i think

3 the problem is here

android devices
android adb interface and it has a ! nothing i try works i keep getting a code 10 ?

looked it up and found one how to that says to delete some things ? but they also claimed it to be dangerous said i should delete these things

See screenshots below

Screenshot_1 Screenshot_2 Screenshot_3 Screenshot_4 Screenshot_5

Just realized something does it matter if usb debugging was on or of ?

Edit: oke so apperntly u can delete them and i deleted the ! one and then i reinstalled them every single one of them in that list i tried wich got rid of error code 10 nomore ! symbol if installed claims device works but none works wtf?

When u update drivers u should go to let me pic from PC then go to downloads and look for universal adb drivers

Go to update driver and device manager and click on forget for uninstall device you need to have a window that says allow from this PC always allow from this PC if you don’t get that window you’re always going to get an unauthorized or you know it’s not going to work right so double check that all you do is you uninstall the uninstall the device from your computer through control panel device manager and then when you plug your phone back in it should beep it should make a noise and then stuff and on your home screen you should get a little window this is always allowed from this PC or this device or whatever and then you click always

I found the folder see below for pci how it looks like.
