Toad Script Runner crashes when rerunning on the disconnected session

I have my sessions running in profiles limiting connect time, so they get disconnected when idle for some time.
When I rerun the script in the Toad Scrips Runner after the connection is terminated by the server it crashes with:
Then reconnecting does not help, the "Execute" button does nothing, i.e. the script is not run. Hitting "F5" and selecting "Run ..." from the menu - no difference - they are consequently ignored.

BTW, it used to be a problem in the "main" Toad's "Execute as a script" up to version 13.1 but not affecting Scripts Runner. Now I noticed it is resolved in the "main" Toad 13.2 betas I was testing, but hitting Scripts Runner...
