Start-up problems since update to v22.5

Yesterday, when I powered up, this appeared:

then this:

It then cleaned (= removed?) 6511 IE Temporary Files and 26 Windows Temporary Files. It optimized the disks but, again, it couldn't analyse them.

I was too busy to create a thread but it's happened again on power-up this morning.

It cleaned (= removed?) 4235 IE Temporary Files and 15 Windows Temporary Files. It optimized the disks but, again, it couldn't analyse them.

I don't believe the figures. How could I acquire/create over 4000 temporary files in a day?

Is this a known issue following the update? What should I do please?

PS I looked in the 'Labels' window to see if there is a label for update problems - there isn't but would a Moderator please change the label "Norton Tollbar".
