The Windows_Portable_x86_64 versions 2.6.0 and 2.6.0 prerelease 10 crash very frequently

This usually occurs when opening multiple session connections at once (such as 5 to 6 sessions), as well as upon software startup (when restoring the previously opened 2 sessions).

The report does not name any source files, tests, logs, or crash details. Start by reproducing the crash in Windows Portable x86_64 2.6.0 and prerelease 10 with five to six simultaneous sessions and with restored sessions at startup; collect crash data and identify the responsible subsystem. Done means the reported startup and multi-session crashes no longer reproduce.
