When trying to load a wallet I last used in 2017 December, in bitcoin core wallet 0.21.0 x64, the UI exits abruptly, last few lines in the debug.log shows the following:

Windows records the crash as follows:

Any ideas why this could be happening? db.log is empty btw..

  • I am having the same problem (with different dates and using the cli version). My post. Your situation seems to indicate that the problem I am having is not related to platform or gui vs cli, which is helpful (at least to me). So thanks.

Check this file: ErrorFile=d:\btdata\db.log

Errors are logged in there. You are viewing the debug logs which will not print any error.

  • Thanks, checked that file however it's empty as mentioned in my question. Feb 11, 2021 at 13:50
  • Did you try reindex and rescan option ? Feb 16, 2021 at 6:20
  • I tried rescan but not reindex, will try that.. Feb 16, 2021 at 18:29
  • 2
    --rescan --reindex allowed me to load the wallet. Thank you! Feb 17, 2021 at 6:30
