I am using LuaLatex and have a pretty strange problem for me regarding Biber and Biblatex. MikTex tells me my installed versions for Biber and BibLatex are: biber-windows-x64 (2.16) biber-doc (2.16) biblatex (3.16)
However, when I want to compile my main.tex through TexStudio it gets stuck running continuously with only minor warnings in the main.log.
My main.blg-file on the other hand tells me the following:
[0] Config.pm:304> INFO - This is Biber 2.12
[0] Config.pm:307> INFO - Logfile is 'main.blg'
[27] biber-MSWIN64:315> INFO - ===
[51] Biber.pm:371> INFO - Reading 'main.bcf'
[171] Utils.pm:209> ERROR - Error: Found biblatex control file version 3.7, expected version 3.5.
This means that your biber (2.12) and biblatex (3.16) versions are incompatible.
See compat matrix in biblatex or biber PDF documentation.
[171] Biber.pm:114> INFO - ERRORS: 1
How can I solve this issue? Where I have to look for?
Thank you a lot in advance.


where biberto check which one is used. And check for updates in the miktex console in user and admin mode. – Ulrike Fischer Jun 16 '21 at 09:42where biber. – moewe Jun 16 '21 at 15:43\documentclass{scrbook}including only the packages I really need for now. Maybe this was the issue as well eventhough commented out most of the options of the templates. – SvA Jun 17 '21 at 13:56
