Having same issue. New to Rstudio. Installed on win10 from package that includes ROpen. Run successfully in early July.
I no longer am able to run it (see err above).
After uninstall / reinstall (multiple times, trying to clean up previous files) of latest packages, I am getting same error.
In the latest "rsession-user.log" the first line is:
05 Jul 2019 03:10:54 [rsession-mad] WARNING Abort requested; LOGGED FROM: bool __cdecl rstudio::session::connection::checkForAbort(class rstudio_boost::shared_ptr<class rstudio::session::HttpConnection>,const class rstudio_boost::function<void __cdecl(void)>) c:\jenkins\workspace\ide\windows-v1.2\src\cpp\session\http\sessionhttpconnectionutils.cpp:140
Obviously, c:\jenkins... does not exist on my machine.
In addition, I discovered that the only Java-JRE installed is a 32bit version, updated during a period when I did not use RStudio.
I am hoping that these details would help point me to the proper solution.
Many thanks,
