Hi. Updated to 5.3.4. and after that there was a problem with new users. The new user cannot log into the system, the system crashes. How to fix? The error does not give any text to copy. Can new fields affect the error? 
What was the crash. Show us the report please. You should have something in documents/sambapos and the log.txt
The crash happened on save?
If I was to guess I would think it’s the name

Looks like you may have two of same user.
Run this report and see if you have any duplicate users:
[Duplicate Users:2,2]
>>Count|Name
{REPORT SQL DETAILS:SELECT COUNT(*) AS Count, Name FROM dbo.Users GROUP BY Name HAVING COUNT(Name) > 1:F.Count,F.Name}
I get a different stack trace when I create a duplicate user and login. It looks like your crash happened when trying to confirm admin pin.
