I'm afraid Plasma 5.19.5 is unfortunately no longer eligible for support or maintenance from KDE. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one. Please update to Plasma 5.27 as soon as your distro offers it to you. If you need support for Plasma 5.19.5, please contact your distro, who bears the responsibility of providing support for older non-LTS releases. If this issue is still reproducible in either Plasma 5.27 (the current LTS version) or Plasma 5.27.7 (the latest released version), feel free to re-open this bug report. Thanks for understanding!
