ERROR - Doktorarbeit.bcf is malformed, last biblatex run probably failed. Deleted Doktorarbeit.bbl INFO - ERRORS: 1 - bibliography

Question

I have Biber 2.17 and TexLive 2022.
I tried to update biber, latex, bibtex, trash aux-files - nothing helps.
Everything worked very well (including references and bibliography) and I suddenly got this error.
There is an error when I try to compile:
INFO - This is Biber 2.17
INFO - Logfile is '.blg'
ERROR - .bcf is malformed, last biblatex run probably failed. Deleted .bbl
INFO - ERRORS: 1
My .log file is:
