Problem repeatedly occurred" error in Safari 15.0

Updated software. Safari 15.0 now won't work.

Can't use eBay. Reloads until error message "a problem repeatedly occurred"

Been deleting/disabling things but won't work.

Turn off “Enable Javascript” in Safari: Preferences: Security, won't work.

Cant use Safari Technology Preview. Wont work with Catalina.

Wont reinstall the Mac operating system. Thats bullying from Apple.

WE pay for something, that is supposed to work and did, Apple cockup. Apple fix it.

I read the same error in Safari 14. No problem until the last 2 updates, 15..

Fix it unless you are useless at your job you're been paid for.
