Failed to open VBOX (Nvram unsupported_format)
Hello I have 7.2.0 r 170228 (Qt 6.8.0 on windows) Virtual box. One of my machines (rest are working well) is sudenly unable to open giving me this error communicate : Failed to load the NVRAM store from the file (VERR_VFS_UNSUPPORTED_FORMAT). Have done a copy of this VM folder, I have money there so I can't affor myself to lose it. Got any ideas how to run it? Found that solution saying that I should replace NVRAM file : https://forum.manjaro.org/t/win11-guest-created-with-6-x-virtualbox-no-longer-booting-on-7-x/131563/9 but cannot follow it, when I created new machine there's no NVRAM file in file explorer there so I can't just copy and replace it. Im very novice in VBOX and computer terms so every help will be very appreciated :) Tried repair it with chat gpt but it just wasted my time..
