KB5015878 unable to get past blue screen on black

I was offered the above update yesterday and allowed it to update.
When it finished it got to the the blue screen with black surround. I was offered a series of choices, namely user Welcome or Hello and link laptop and mobile phone. I don't remember the others.

The problem was there was nothing I could click on to allow me to access the options. It was as though the font size had been changed so that some of the text had been truncated, but I hadn't changed any of my font sizes for years.

For a while I was stumped as to how to get past this point and I eventually forced a reboot and I no longer get the blue screen.

Is this a known problem and is there a fix? My Winver is 21H2 (OS build 19044.1865).

Is it possible to access the options on the blue screen anyway else?

I should have taken a print screen of the blue screen but didn't think of it, but it is the same screen that appears after some updates have completed.

Suggestions welcome please.

Thank you

Hi Dalchina, thanks for response.

I have now updated my specs, sorry, I haven't been on here for a long time so had forgotten.

So, I am currently on 21H2 (OS Build 19044.1865).

In all honesty I confess to all that being above my head, and reading that it is best to keep my system up to date I have been doing so. And as for being a Preview version I ought to have paid more attention and not installed it.

So, would you suggest I uninstall it?

Thanks

It didn't show up in the View Update History but it did show in Uninstall programs list, so I have removed it.

I wasn't receiving downloads for Insider Preview anyway.

Thank you for your help.
