The crashlog will show it. It does not matter which program you use to get the crashlog, WinSCP, Filezilla, samba share etc. You just want to transfer the file to your PC so that you can then upload it to this forum for people to help you.
Something you restored is causing the problem. You can reflash the image again and not re-install older plugins/settings. You will have to start from scratch. I don't see any benefit in going to 6.2, The main difference is 6.2 uses python 3.10, 6.3 uses python 3.11.
