Since updating to 2020, I get at least two crashes every 8 hours of work and it will only recover the oldest loaded document if more than one document was open at the time of the crash. Prior to 2020 I rarely had Photoshop crash and even when working on several documents they were all recovered where I'd left off. Now it recovers the oldest and seems to leave off the last two or three steps prior to the crash. This has been consistent now through a dozen crashes in the past few days since upgrading to 2020 on the new iMac. I am not having this issue on an older MacBook Pro i7 running Catalina by the way. Just the new 5k iMac.
