Not that I know of. Most crashes are spontaneous and of new origin - the devs do a fantastic job of dropping patches for critical bugs like that. In terms of keeping your stuff better after crashes through, try exiting through a loading screen every half hour or so. That should force the game to save. Oh and beware, some doorways aren't loading screens, mainly those into small buildings, so watch out for that
However, if you were grinding for a long period of time, the game may have made a backup of your progress. If you navigate to %appdata% > Secrets of Grindea > Backups, and sort the folders by date, find your character and then sort the files by date, I
think the files with the prefix "auto" are made at fixed time intervals (don't quote me on that). Regardless, renaming them to "0.cha" and "0.wld" for slot 1 or "1.cha" and "1.wld" for slot two etc. and then copying them into the Characters and Worlds folders, you might find you get the stuff back. I'd suggest uploading them into an empty save slot so you keep your current file if anything does go wrong though. If I went through that too quickly there's a video in the spoiler below.
Did you end up submitting the error report after the crash? That would allow the devs to know what happened.
Hopefully the backups restore your progress - some of those Tai Ming cards took ages for me to grind, I can imagine the pain
