Search a comment in a PDF file

Hi,

I cannot search a comment in a PDF file using the file explorer in Win11. 

My Win10 machine is able to pull every PDF file.  I basically tried everything from the search settings with no success.  It can find regular text but if it's in a comment Win11 will not find it but Win10 will

I really need to go trough lots of PDF,  and was able to do it just fine on my Win10 machine. 

Thank you
