I see you used a boot image. Does this model have a recovery partition (recovery.img)? If yes, use that instead

Try this and let me know how it goes
After installing this on my active slot, it boots fine into a safe password, that I don't know but any password will tell its right but requires a wipe, after the restart, it keeps on a bootloop

Share a picture of the screen showing the password mode.
You should have tried fastboot boot first instead of fastboot flash.
Anyway, fixing it isn't a problem. You just need to get into bootloader, then flash the stock boot image.
Alternatively, you could use SP flash tool.

The password entered is correct, but the data is corrupted.
To continue using your smartphone, you need to reset it to its original settings. When you set up your smartphone after the reset, you will be able to restore all the data that was backed up to your Google Account.

Enter the password to unlock. 30/30 attempt(s) remaining.
To change the settings, go to Security settings.
You either do a factory reset or flash back the stock boot.img so you can move important stuff.

already did that, then when it reboots, it wipes data, like if that modified boot file couldn't do this
Also shouldn't the boot file be like 40mb? like the original file
