I wiped everything in trwp when I was going to install Lineage, I did the misstake to restart the recovery and now Im stuck in the bootlaoder.
I need to install the stoc firmware via fastboot/bootlaoder but can't find any img file, only zip file of the Stock firmware.

I have never tried msmtool, but it sounds like a driver issue. Maybe take a closer look at their instructions
You can try these fastboot flashable stock roms.

You have few options to solve your issue. Now you are in slot B. You can change switch partition to A with fastboot. Try use: fastboot --set-active=a. It will switch to partition A and then try to boot/flash recovery. Also you have try to use fastboot roms with flashall.bat. There are few availaible in forum.
If you would like to use MSM you have to connect phone in proper mode to PC. Power off and hold Vol+ then connect. Also try to install latest Qualcomm drivers.

Msm tool
Download and use msm tool

You must not have followed the step correctly to flash rom with fastboot method. I assume you have adb and appropriate drivers installed on your pc. Download the zip file from the link in that thread on your pc. Unzip the file. Put your phone in bootloader mode. Connect the OnePlus 6 to PC; Run flash-all.bat file from the folder where you unzipped the ROM. It worked all the time for me and many others.

Installing TWRP on Gome U9

But when the phone boots, it just boots normally. If I power off the phone and boot into the options and select 'Recovery', it just shows the standard options. It never boots into TWRP.
first you need to unlock the bootloader, and then install twrp

The bootloader was unlocked. I figured out what was happening and now it's working. If you run 'fastboot reboot' after installing TWRP is falls back to the default recovery. The key is to boot into recovery again after installing TWRP via the Volume Up/Power buttons.

Make sure you are using the latest TWRP img.
Never flash recovery. Always boot recovery and then install TWRP zip. Have you not read the instructions?
As others mentioned, easier way to recover TWRP is to flash a magisk patch boot.img and flash TWRP zip in magisk.
Thanks for the tips guys, all sorted!

OK:
1. First you need to root the device. Follow this guide. You will use adb to patch the boot.img file of your current firmware.
2. After you have rooted, you can install the unofficial TWRP for Android 10 Moto G8 Plus from here. The zip file will install through magisk. Works fine; I tested it last night.
