I have a problem. I just booted into a clean Sequoia installation that is just sitting there on another partition waiting for my never happened downgrade since months.
I started Disk Utility and ran first aid on all four "damaged" internal HFS+ partitions that only included bootable macOS installers. They were not damaged in Sequoia and I also was able to delete them all what didn't work in Tahoe.
Now these error messages after rebooting are finally gone:

Strangely they never appeared for the Ventura and Sequoia installers but they had the same issue.
So if someone has a problem with an (external) HFS+ drive. It is not really damaged. Only the recent Beta of 26.4 has a problem using it. It seems all "damaged" mostly external drives can be used normally again when this is hopefully fixed in Beta 2.

I wonder if I still get those fsck_hfs process crashes now that all my HFS+ partitions are gone.
My problem now is... I saw Sequoia again and it was soooooooo beautiful! 💖 🙈
