Error when selecting either a milestone or change request

Hello
V11.4.3

I have a user, as soon as he selects either a milestone or change request for examples, he receive this error message

 

Here is the error in the log file

2025-01-08 08:36:10.278 ===== TRACE ===== [493] NEW CONNECTED USER 'ehache'

Thanks

I found i workaround

i remove line 168 to 180 from file ChangeRequestMain.php

After removing those line, we can now enter Change Request and make modification

UPDATE i have this error only in Change Request  (i mentionned milestone but that was not exact)

Regards
