The attached is tentative fix for cases like the above.
It gets rid of the observed error, however I am not sure if the clock
line parser returns a reasonable value is such case. With the patch,
org-element-at-point returns

(clock (:status running
       :value
       (timestamp (
                  :type inactive
                  :raw-value "[2021-10-22 Fri 10:41]"
                  :year-start 2021 :month-start 10 :day-start 22
                  :hour-start 10 :minute-start 41 :year-end 2021
                  :month-end 10 :day-end 22 :hour-end 10 :minute-end 41
                  :begin 301 :end 323 :post-blank 0))
        :duration nil :begin 294 :end 331 :post-blank 0 :post-affiliated 294))

Should we consider the above CLOCK line as a valid running clock or
maybe it should be parsed as a paragraph?

Best,
Ihor
