Hi @Jindrich Zerzanek,
Welcome to Microsoft Q&A!

Please restart your computer to check for Windows Update and install all available updates. If you have any anti-virus software, please temporarily disable them.
If it doesn’t work, please use the DISM or System Update Readiness tool to fix your Windows Update error.
Sincerely,
