After Effects CC 2019 & 2020 --- After Effects Error: File Exists but couldn't be open for reading

[bbab22]

Last week, I updated my mac with the latest version of Adobe After Effects 2020.  I still kept the CC 2019 version installed just in case I had a difficult time opening my files.  Now when launching either CC 2019 / CC 2020 version of After Effects, I cannot open any of my previously created after effects files whatsoever.  I am getting the error message: After Effects Error: File Exists but couldn't be open for reading: "FILE NAME.aep" ( 3 :: 0) . At this point I really have no idea what to do to move forward. Any help is greatly appreciated.

Same here. Adding my voice onto here so that Adobe sees how much of an issue this is. My problem is with BRAW files as well. Thankfully my project only needs a handful of clips, so I only need to mash enter a few times to get around it, but his is far from acceptable for a program I depend on for my career.
