Is it possible to recover current track after clear cache?

Locus kept on crashing while recording a track yesterday, so I cleared the cache and temp folder. But after restart it started a new track and there is no sign of the old one. Is it possible it is still stored somewhere and recoverable?

Also, why did it keep crashing? I noticed today that the log file is 27Mb and seems to contain mainly messages about getTrackGroups not being able to connect to the internet. On other days with similar usage it is about 250kB. It seemed to be worse when following a route.

Locus v4.30.1 on Samsung Galaxy S8+, Androod 9.
