Convert week number and year to a date in Access-SQL?

Question

In Microsoft Access, I have a table where number of hours worked per weekday are associated to a project number, ISO-week number and year. Simplified, it looks like this:

ProjectID	WeekNumber	YearNumber	Monday	Tuesday
1	1	2022	5	6
1	2	2022	7	8

I am trying to set up a query where all weekday columns (monday to sunday) are "merged" into one column and the week and year numbers are converted to dates. It should look like this:

ProjectID	Date	HoursPerDay
1	03.01.2022	5
1	04.01.2022	6
1	10.01.2022	7
1	11.01.2022	8

I managed to merge all weekday columns into one column using a UNION query:

SELECT ProjectID, WeekNumber, YearNumber, Monday As HoursPerDay FROM ProjectHours
UNION ALL
SELECT ProjectID, WeekNumber, YearNumber, Tuesday As HoursPerDay FROM ProjectHours;

The result looks like this:

ProjectID	WeekNumber	YearNumber	HoursPerDay
1	1	2022	5
1	1	2022	6
1	2	2022	7
1	2	2022	8

But I am stuck converting the iso-week and year number to a date. Is this at all possible in Access-SQL?

I found this question on Stackoverflow and went through the date/time functions that Microsoft lists for Access but could not get it to work.

Any help is highly appreciated.

EDIT: A community member has suggested a possible duplicate of this question, but I am looking for a solution that I can use in an Access-SQL query, so the suggested duplicate does not help me, as it suggests a VBA based solution.
