Impossible to run scripts due to hanging debug session (ISE Editing session)

[alan-null]

Expected Behavior

No errors, I can run scripts in ISE.

Actual Behavior

Steps to Reproduce the Problem

• Open ISE (http://domain/sitecore/shell/Applications/PowerShell/PowerShellIse?sc_bw=1)
• paste this script

Write-Host "Start"

$empty = "EMPTY"

• toggle breakpoint on line $empty = "EMPTY"
• run debug (using Debug button)
• press F5 (refresh a page)
• try to run script (using Execute button)

Additional info

When I switch session mode to Single execution it woks fine but using ISE Editing session is impossible. You have to restart instance or wait long time.

Was this ever fixed? I am experiencing the same issue on latest version of SPE.

[alan-null]

@marcdepelteau No. The bug state is still Open

[marcdepelteau]

Ah okay, I saw that @michaellwest removed it from the to-do list, so I figured it might have been fixed.

Problem still exists on 5.1.0.19766 on Sitecore 9.1.
