windows 11 Windows 11 mounting .iso files problem

[Sten.]

Hello

 

Recently I am having strange problems trying to mount iso files on Windows 11, before there's no issue at all. 

When I tried to mount iso files, it comes up with two different issues

1. 2 Errors appear: - "Windows can't access this disc, the disc maybe corrupt. Make sure the disc uses a format that Windows recognises. If the disc is unformatted, you'll need to format it before using it"

                               - on the back of the above error it also says "Couldn't mount file : The disc image isn't initialised, contains partitions that aren't recognisable or contains volumes that haven't been  assigned drive letters. Please use disc

                                 management snap-in to make sure that the disc, partitions, and volumes are in usable state.

    (at this stage, a virtual disc drive appear but blank) and the "Windows can't access this disc, etc etc as above appears everytime I click it)

2. Iso files mounted and a virtual drive appears and seem successfully mounted the iso file, but upon inspection only a tiny fraction of the file size is actually mounted. (ex: iso file is 12 GB, but only 123 Mb in the virtual drive) and won't work when I

    tried to run the files.

 

I tried every possible fix guides online, but none work. I do not install nor changed anything recently aside from Windows updates. No malware, virus detected. It was still working fine around the end of February 2022 for sure.

if I use 3rd party iso mounting apps like poweriso, it works without issues.

 

Anybody might be able to help?

Thanks
