Trying to upgrade Koritha gear, had to disable add on

1x [ADDON_ACTION_BLOCKED] AddOn 'HandyNotes_Shadowlands' tried to call the protected function 'GetPlaystyleString()'.
[string "@!BugGrabber\BugGrabber.lua"]:519: in function <!BugGrabber\BugGrabber.lua:519>
[string "=[C]"]: in function GetPlaystyleString' [string "@FrameXML\LFGList.lua"]:3508: in function LFGListUtil_SetSearchEntryTooltip'
[string "@FrameXML\LFGList.lua"]:2576: in function <FrameXML\LFGList.lua:2573>

looks to me like it is "LFGlist" addon not handynotes

I don't have that add on installed, and from reading that add on has been broke since 2019. What about world quest list, I do know sometimes that add on affects upgrading Korthia gear, however when this error popped up it WQL was disabled.

OK after investagting this LFGlist.lua it is a Blizzard UI interface (the korthia gear upgrading?) I did serach of my add ons and it found no LFGlist.lua

what I would suggest is you turn off ALL addons except handynotes and try the issue. If it still happens then you know for sure.
if it doesn't happen then turn things on one by one until you narrow it down.
I can't see any logical reason why handynotes would cause this issue.

Having the same issue, Did you ever solve this issue or find the cause lovs2build ?

Do you have world quest list? This is what was causing it for it, when I disabled it, I had no problems, if not then follow advice by creator of addon below my OP to figure out which addon is causing error. Good luck
