These are cached and not unloaded when the app exits. When you load that application version in this directory it will load those. If you watch when he opens the Folder of the original app you will see a bunch of. Gee I should go to his video and and warn him. But it just sits there flashing all 4 battery lights till you let go the button. I tried pressing and holding the Battery button for 3 seconds and waited for the beep to say it was ready to bind to the TX. You PC / Mac will recognise the Sparks on board SD-Card load the correct Device driver and mount the SD card as a removable media device. The TX will never connect and it will not be recognised again by the Assistant ap. Does it self tests a and flashes yellow as if its waiting for the TX to connect. The status of the Bricked spark is that it switches on like normal. I am suspecting that its not just the Spark and assistant version but the actual database for your location. Thats a pity, did you use a Mac? And what country are you in. Should I wait to return if a new Assistant would fix or send it away for 6 weeks to just get another one in the mail ? For 3 hours I tried various things with the help of a very knowledgeable DJI friend but to no avail. Used the newest Assistant and my Spark is bricked. I totally just did this last night at 7pm. So you have not had the same experience that the OP had with a compatibility issue with the Mavic Air DJI Assistant version causing issues updating other products?

Just my opinion based on my experence so far as a DJI product user. It is not an uncommon issue and if a version is not posted on the support page for the product you are updating I suggest you should assume you are taking a compatibility risk. I am only pointing out how dangerous it is to make those kind of assumptions about DJI's software compatibility across their products. I agree with you that Assistant should work across all of DJI's products. I personally have connected a Spark, Mavic Air, Mavic Pro and Phantom 4 Pro to the latest version (V1.2.2.827) with no issues at all. You can only have one version installed on your PC at a time and those of us that have several different drones need to be able to talk to all of them Therefore, I have the latest since it supports the Air.
