You need to apply the size to the modal-dialog element, as shown in the documentation:
Optional sizes · Modal · Bootstrap v4.5[^]

If you want to set the width inline, you'll need to use the correct syntax for the style attribute, and set the max-width property.

HTML

<div class="modal-dialog" style="max-width:75px">
