I, too, can confirm that blocking cookiebot.com solves (at least a lot of) problems. I observed some of the issues mentioned above since yesterday. Also, I had do deactivate the Tampermonkey Mystery Wizard script to have logs displayed again.
After blocking cookiebot.com via uBlock, pages load faster and completely, even after I activated Mystery Wizard again. So, I expect the cookiebot stuff to be implemented incorrectly.
