Retrieve data from OnePlus 6 device in Qualcomm Crashdump Mode

[au_an]

My OnePlus 6 all of a sudden froze and went into Qualcomm Crashdump Mode. I tried restarting it normally, in fastboot mode and also recovery mode, and 9 out of 10 times it just reboots to show the same Qualcomm Crashdump Mode page. But occasionally it does seem to boot the phone normally and I can see my lock screen and access my apps & data, but within 30-40 seconds it just freezes again and reboots and goes to the Qualcomm Crashdump Mode. That 30-40 seconds isn't sufficient to copy across all the data I need. Is there any way I can copy or retrieve my data from this device?

I tried doing a cache wipe in recovery mode but that didn't help either.

Hi, welcome to AC !
You messing with secret dialer codes?
Most likely going factory reset

You don't regularly back up your data?
