I have dug into this a bit more and turned on the postmaster log
This statement fails if the first parameter is "abc" but works with "abcde"
SELECT "Id","Begin","End","Logfile" FROM "ServerSession" WHERE "Logfile" = ? ORDER BY "Begin" ASC OFFSET ? ROWS FETCH FIRST ? ROW ONLY
The postmaster log with "abc" (cbColDef and cbValueMax both 3)

2024-09-19 12:20:26.092 CEST [17828] STATEMENT: SELECT "Id","Begin","End","Logfile" FROM "ServerSession" WHERE "Logfile" = $1 ORDER BY "Begin" ASC OFFSET $2::int4 ROWS FETCH FIRST $3::int4 ROW ONLY
The postmaster log with "abcde" (cbColDef and cbValueMax both 5)
2024-09-19 12:20:26.092 CEST [17828] LOG: execute <unnamed>: SELECT "Id","Begin","End","Logfile" FROM "ServerSession" WHERE "Logfile" = $1 ORDER BY "Begin" ASC OFFSET $2 ROWS FETCH FIRST $3 ROW ONLY

By changing the statement a bit (using OFFSET ? and LIMIT ?) it works with both with "abc" and "abcde"

There's a lot of fishy things going on (where subsequent parameters sometimes seems to be serialized as strings depending of the size of earlier string but not always), but I won't speculate of the reasons
We want to use the OFFSET ? ROWS FETCH FIRST ? ROW ONLY statement
