SonarQube C# Analysis Fails to 'Not a Valid Line Offset for Pointer'

I have projects that I've been analysing with SonarQube succesfully for a while, but now I'm having some errors. The exact error is:

12:26:01.413 ERROR: Error during SonarQube Scanner execution
java.lang.IllegalArgumentException: 74 is not a valid line offset for pointer. File [blaablaablaa...] has 70 character(s) at line 118

I have updated the C# analyzer to the latest (5.10.1 (build 1411) installed). At least the update center doesn't provide a newer?

I also updated the scanner to sonar-scanner-msbuild-2.3.2.573

I'm using SQ 6.3.1.21392

There are quite a few similar posts here in SO, but all of them are pretty old and they suggest that it's either a known bug in the analyzer or an encoding issue. I've tried to change the problem file encoding to plain UTF-8, but that doesn't resolve the issue. Notepad++ shows the encoding is UTF-8-BOM. I've also used the bomremover, but that doesn't change the error at all.

Any suggestions what to try except to exclude all the problem files from the analyse?

EDIT
The encoding of the file is UTF-8-BOM, but it makes no difference to convert it to plain UTF-8.

File encoding of the problem file

I used Notepad++ convert to UTF-8 and re-run the analysis. Same error as a result and here's a screenshot of the new encoding:

I found this issue was caused for bad LF format, using MAC (CR) LF on windows.
