Why does TR[GA5.GA5] cause an error(IterationLimit) in FeynCalc 10.1.0?

Why does TR[GA5.GA5] cause an error(IterationLimit) in FeynCalc 10.1.0? While in FeynCalc 10.0.0, it's ok.
And why TR@DiracSimplify[GA5.GA5] works? Is there anything wrong with GA5?
Thanks for your instant help.

I think it was a bug introduced somewhere in between, but it is not there anymore. Please reinstall FeynCalc and check again.

Thanks for your patient reply, but I'm sorry to disturb you again since when I updated my FeynCalc, I find problems below. May you tell me is there anything wrong with my code?

Thanks for pointing this out. Could you please try the latest version again?

IterationLimit still appears with TR[GA5.GA5.GA5] after I updated FeynCalc.

Are you sure that you updated the *dev* version to the latest snapshot? This particular example works for me. Am 27.03.25 um 07:31 schrieb ZIXIOUYANG:
