If the slides are hidden, diagnose an open-password case. If the deck is visible but editing is blocked, inspect modify protection, Protected View, and permissions first.
A password requested before PowerPoint displays slides protects access to the presentation. Keep the original PPT, PPTX, or PPTM and record the Office version and dialog text. A file that cannot open needs a different path from a deck that is already visible.
Recovery process
A password requested before PowerPoint displays slides protects access to the presentation. Keep the original PPT, PPTX, or PPTM and record the Office version and dialog text. A file that cannot open needs a different path from a deck that is already visible.
If slides are visible, check whether PowerPoint asks for a password to modify, opens in Protected View, or is shared with view-only permission. Microsoft describes these as ways to prevent changes while still allowing a presentation to be opened or copied. You may need an authorized editable copy rather than password recovery.
Work from a copy and do not convert the presentation before diagnosis. PPTM can contain macros and presentations can include media, notes, fonts, and links that may change during conversion. Submit only a presentation you own or are authorized to process.
These details help with the first profile check.
The outlook depends on the actual encryption profile.

Next step
Start with format detection and choose the appropriate path only after the file is identified.
