I am using the default CSS theme and I have the same issue. Same OS and version.
I should add that the rendering in the Preview shows the footnote correctly.
For some reason there seems to be a “misuse” of the syntax for footnotes. The right syntax is ^[text] and NOT [^text] . If you use ^[text] you can have a footnote related to a bullet point rendered correctly. All my footnotes done that way, incl. in bullet points, work perfectly in Obsidian.
See lengthy discord discussion between myself and @Klaas, finishing with mutual understanding that both syntax’s are right, because there are two different ways to write footnote markup!
To me then
a) this bug, as reported needs fixing and
b) the Obsidian help files should also document the “inline” footnote markup used by Klaas
