Help Restart issue - HELP PLEASE

[DashiDash]

Hi,
My galaxy S20 recently crashed and a restart was forced.

Once the UI was rebooted, as always, the notification comes up advising that the restart had occurred and to unlock the phone to get other notifcations, however, when I go to unlock my phone, the screen flashes black, then it goes back to the lockscreen with the restart notification again.
I can't powerdown the phone either as it requires the lockscreen to be taken off.
If you try too many times to unlock the phone, the UI will switch to safemode and the same thing happens.
A continuous restart/lockscreen loop.
Any help would be appreciated; especially if it means I can keep all the data on my phone without a full wipe.
TIA.

hold the power button down until it reboots or powers off.

Try restarting your phone into its Recovery Mode and select the 'wipe cache partition' option. Instructions on how to get into Recovery here:

Note that Recovery is text-only mode (use the indicated buttons to navigate through the various options), and that wiping the system cache partition won't affect your files/data. But be careful, the factory reset option is listed just above the wipe cache partition option so pay attention to what you select to do as a factory reset will wipe all your files/data.
Since you are seeing that Lock Screen message pop up though, you might also want to try starting your phone up into its Safe Mode and see if your phone will boot up without boot looping:

It will be trickier to get into in one of these other startup modes since they involve pressing the right buttons in sequence. Timing can be a factor too so don't be surprised if it takes a few attempts until you get accustomed to what to do.
