Hello Anne,
just some ideas.
At the end of your screenshot: I am not sure, if _ is valid at the beginning of a SPSS variable name, see IBM Documentation
Variable names can be up to 64 bytes long, and the first character must be a letter or one of the characters @, #, or $. Subsequent characters can be any combination of letters, numbers, nonpunctuation characters, and a period (.). … Letters include any nonpunctuation characters used in writing ordinary words in the languages supported in the platform’s character set. .

Maybe also to try import as UTF-8.
Could the […] brackets in the labels create a problems? You might try with a simple example and change them to (…) or remove them. You may just try: start "start {test}'.
All your error msg refer to Spalte 3 (column 3) and all cases have a [ …] there. But I think, it’s ok, as
Variable labels can contain any characters, including blanks. To enter an apostrophe as part of a label, enclose the label in double quotes or enter a two apostrophes (two single quotes). See IBM Documentation
Also, your variable named Date might create a conflict with the SPSS DATE command.
Would like to hear about your solution, please.
Kind regards
