Crash on Editor startup - Runnable thread FAssetDataGatherer crashed.
For a while now I've been deleting the contents of the folder DerivedDataCache to (temporarily) save space as I understand it re-generates itself from uasset files anyway.
On this occasion however I'm no longer able to open my project at all! I've affixed the logs below.
Really appreciate any help! Although I have version control on my code+blueprints I have not archived my entire project folder in a while so I'm basically stuck at this point :(
Note that I have tried regenerating the DDC manually using the "Building Derived Data" fill command described on this page, that didn't fix the crash (although it does seem to have regenerated stuff)
PS: I realize this is less of a bug report and more of a mess I've created on my own but I couldn't think of a better section for the issue, appreciate your assistance!
Fortunately I found a workaround, hope this helps others:
I think I'm going to stay away from misadventures with DDC files henceforth! I'll probably make a symbolic link from my SSD to HDD for DDC folders alone. I'm not sure how often read/write operations are done on DDC files so it is unclear how much this will slow the editor down for me.

For anyone else having this issue, make sure to check that you haven't added any asset packs that aren't from the correct engine version. That's what it was for me.
