Power BI Report Server October 2020 update has been released.
I managed to fix this. I tried a fresh install on my own PC and everything worked fine, which led me to think that something was messed up with the update process. I then turned off the Power BI service on the server, renamed C:/Program Files/Microsoft Power BI Report Server, and ran the installer again with the "Repair" option. Once it was done, I copied the config files from the old install folder to the new one. These files were:
C:\Program Files\Microsoft Power BI Report Server\PBIRS\Portal\RSPortal.exe.config
C:\Program Files\Microsoft Power BI Report Server\PBIRS\PowerBI\RSPowerBI.exe.config
C:\Program Files\Microsoft Power BI Report Server\PBIRS\ReportServer\rsreportserver.config
C:\Program Files\Microsoft Power BI Report Server\PBIRS\ReportServer\rssrvpolicy.config
C:\Program Files\Microsoft Power BI Report Server\PBIRS\ReportServer\web.config
C:\Program Files\Microsoft Power BI Report Server\PBIRS\RSHostingService\RSHostingService.exe.config
I don't know that all these configs were necessary, but I copied them anyway just to be safe. Also, I did not try just doing a straight repair first...that might have been enough to fix it. The rename/repair/replace definitely fixed it. Now my dashboards that were broken are refreshing like they should.
