MySQL 8 installer fails early in the installation routine

I am trying to reinstall MySQL 8 on a Windows 10 machine. MySQL 8 was previously installed on this machine and worked just fine. A few days ago, the entire modules directory in the Apache installation disappeared. At that point, I uninstalled Apache and MySQL and did a thorough inspection for viruses and other malware. The results for malware were negative.

I then reinstalled Apache which successfully installed. When I attempted to install MySQL 8, however, the installer simply died very early in the installation, when a little dialog box says that it's configuring MySQL for installation. The Windows Event Log identified an Event ID 1000 associated with the MySQL installer failure. At that point, I ran SFC and DISM, both of which found no corrupt files.

I created an entirely new user profile on this machine and attempted the installation from that profile. The results were identical to what I experienced with the original profile.

I completely uninstalled and reinstalled the entire .NET Framework and ran a complete CCleaner Registry scan and did a full repair of all issues found. I have Malwarebytes Anti-Malware installed and disabled it throughout all the issue resolution steps. After all of these efforts, the MySQL installer (I tried both the Web and the Community installers, both of which behaved the same way) continued to fail early in the installlation routine at the point where it said that it was configuring MySQL for installation. The only thing that changed was that the Event ID changed from 1000 to 1001 CLR20r3. The entire Event Viewer contents follows:

Fault bucket 2190365724986395993, type 5
Event Name: CLR20r3
Response: Not available
Cab Id: 0

Problem signature:
P1: MySQLInstallerLauncher.exe
P3: 5b749705
P4: MySQLInstallerLauncher
P6: 5b749705
P7: 4
P8: 0
P9: System.IO.FileNotFoundException
These files may be available here:

Report Status: 268435456
Hashed bucket: 16c77f3607d120b16e65be0596014d59

I would greatly appreciate any help, suggestions, or guidance that anyone can offer. I really need to get MySQL installed and running on this machine as quickly as possible.
