This was encountered while investigating an issue where design time builds were very slow. It turns out, EndBuild failed, leaving the DTBB service in an invalid state, causing CPS based projects to fallback to the slower, legacy build pipeline.
The DTBB service is being improved to better handle EndBuild throwing exceptions. However, this exception may still be thrown. Also, repeated opening and closing of the file may be less performant than keeping the file opened, and could be locked by the antivirus.
For more details, please refer to the internal devdiv item AB#2235125
