For the deletion part, I don't know whether or not this issue is actually from that due to my antivirus being triggered whenever I try to launch the current version of SDF Modeler--as I assumed that it might've been an error in the file or program itself (or just Windows 11 being Windows 11 😂), but using McAfee Total Protection, I did another test where I inserted the file from the ZIP archive file into a test folder and scanned just the file itself. McAfee picked it up as a "threat" [ti!6C7D6B7BD72A] and deleted it (in this case, quarantined).
I don't know if I'm checking the right repository for meshoptimizer, but I did see that another person had experienced this false positive where Windows Defender also picked it up as a trojan.
Totally not forgetting to post this reply, SDF Modeler seems to work again after adding the file as an exclusion.
