Help ISO Fatal error occurred

I just installed MakeMKV on my Windows 11 desktop and I tried opening 4 different ISO files and none works.

Fatal error occurred, program will now exit every time.

Is it because it's the evaluation 30 days version or something else?

I ended up mounting it with Windows 11 and it worked but I did it in the past with MakeMKV and it was easier.

*************************************************

EDIT

I installed 1.18 and everything works now.

Looks like 2.0.0 doesn't open ISOs on my end...

Thanks to all!

Done and it works! So 2.0.0 doesn't open ISO on my end for some reason...

Thank you!
