Xcode not opening Archives

I thought that the issue would be the "Archives are not showing up on Organizer window" one. After calling on Product > Archive, it will say it has finished successfully, and I can find a folder with the app name, date, and time of said "successful" run.

However, the issue at hand seems to be even bigger: when I try to open the path in Xcode/Archives, it tells me that the archive may be "corrupt or unreadable." Overmore, I have done what old guides and stack overflow posts have said regarding this issue (such as https://developer.apple.com/library/archive/technotes/tn2215/_index.html#//apple_ref/doc/uid/DTS40011221-CH1-XCODE_SUCCESSFULLY_ARCHIVED_MY_APPLICATION__BUT_THE_ARCHIVES_ORGANIZER_DOES_NOT_LIST_MY_ARCHIVE)

This all happened after I updated Xcode (I had to because it wasn't letting me test on my connected device). Any help resolving this issue is appreciated.
I have also tried uninstalling and reinstalling Xcode to no avail.
last week i updated too (xcode 12.1 and catalina 10.15.7), and im running the same issue, if you find any fix please let me know , thanks

I have the same issue. Will try with another xcode verison.
