ms-word:ofv|u|file://test5/T:/folder:/test.docx word opens to blank screen

Hello,

I am connected tho VPN to server that I have saved path to in my PC and have access to files (can open them when using it normally).
When I try to use command ms-word:ofv|u|file://test5/T:/folder:/test.docx in browser but I cant get it to open.

I tried change folder to wrong and it told be, that it didnt find file in that folder, so I think it finds the folder and tries to open it but fails.
And when it opens from right file it informs me its insecure and after confirming Word loads to blank screen (not even white page on background)

I set that file as trusted location, so rn I am on bit of a loss to what to do/try now.

Any tips to what I am doing wrong or what should I try?

Ty for help
