TIFF files wont open

Hello All - I have the most current CC Photoshop Version 23.41.

Yesterday I was moved onto a new PC laptop for work and suddenly cannot open .tif files. Photoshop simply freezes entirely and I have to open task manager to end task each time I try. I have tried reverting to an older version of Photoshop, however this does not work either. 

I tried the below fix to see if it could work; removing the .tif from the naming convention, and no luck here either. I'm at a loss - any help? 

Thank you!

Would help us to know what system you are on. If the file extension is wrong as Herr Pfaffenbichler mentioned, try this:

Do a command I on the file

remove the last letter and the 3 dot filename extension, and if the filetype changes, then you know what if actually should be, as this is pulled from the files resource fork rather than filename now.

if you still have trouble please confirm if this happens for all files, anything similar about the files such as coming from a client or old server. Does this happen to a new file you create and save as tif and try to reopen?

Can you display the tif file with  an image viewer?
