how to fix it ? @chrysan

[chrysan]

@leonirvanel which version is this stack trace from? v5.4.0 or v5.1.4?

[leonirvanel]

V5.1.4

[time-and-fate]

This issue is the same as #35181 and has been fixed by #35298 on the master branch.
It will be fixed in the next major release.
For other release branches, it may be fixed in the next minor release at the earliest, but I'm not sure when would be the next release.
