Cannot flash BLE Wireless Stack into STM32WB55CG (USB Dongle). FUS_STATE_IMG_NO_SPACE

Hello! I'm trying to flash wireless stack into the STM32WB55 USB Dongle.
I've successfully upgraded FUS to version 2.0.0.3.

But now i cannot flash wireless binaries. Each time I try to do this, i'm getting the message, that image is downloaded, verified. Than that image found and authentic, but there's no space.

ERROR: FUS_STATE_IMG_NO_SPACE.

What am I doing wrong?

I've tried many different flash addresses for flashing:
0x080D4000
0x080D0000
0x080CC000
And much more. So i think that the reason is smth else...

Current state of Option bytes:

I didn't change anything here.

I've tried different states of BOOT0 switch on the board, but nothing changed.

I'm not sure, why this worked, but I rebooted the board, then executed FULL chip erase, and than flashed Wireless Stack WITHOUT erasing the flash, and it worked... i'm not sure, if this is correct way to fix my issue, but it worked... After full chip erase i switched to FUS tab and started flashing Stack to 0x080D0000 without doing any actions with FUS (checking ver or state). 
1. Full chip erase
2. Switch to FUS tab
3. Check "No stack delete"
4. Addr = 0x080D0000
5. Upgrade without any previous actions with FUS

 

I guess, maybe communication with FUS to check it's version or state disables further stack upgrade until chip reset? Anyway... Topic can be closed...
