when switching Plasma theme

Product: krunner
Version First 6.5.4
Reported In:
Platform: Other

SUMMARY
I use Koi software which switches light/dark Plasma theme based on time.
When Koi switches theme from light to dark, the krunner usually crashes.
STEPS TO REPRODUCE
1. Switch the theme from Breeze Dark to Breeze with Koi (it switches plasma
style / icons / colors)
OBSERVED RESULT
Krunner crashes, starting from WebshortcutRunner::loadSyntaxes
KAutoWebSearch::populateProvidersList →
KIO::KURISearchFilterEngine::KURISearchFilterEngine
(src/urifilters/ikws/kuriikwsfiltereng.cpp:36) →
SearchProvider::SearchProvider (src/urifilters/ikws/searchprovider.cpp:21)
→ KDesktopFile::KDesktopFile (src/core/kdesktopfile.cpp:47)
→ KConfig::reparseConfiguration (src/core/kconfig.cpp:688), null pointer
dereference.
EXPECTED RESULT
Krunner does not crash
