Multiwfn Failure to Read log file

Hello everyone,
I noticed something strange. So, I have already done an earlier TDDFT calculation on Orca, and I have been using Multiwfn to view the UV-vis plot and recently, I ran a calculation and tried to view it but it keeps failing after selecting UV. I had to re-run the same earlier calculation and I got the same error but if I use the old file, the plot is visible.
For the recent file, instead of using the orca output file, I decided to use convert the file to Molden and multiwfn can't view it either.
Any suggestions?

Re: Multiwfn Failure to Read log file

Please make sure that you are using the latest version of ORCA and Multiwfn. Old versions may have incompatible problem (ORCA frequently changes output format among different versions). If you are indeed using the latest versions, please send your ORCA output file to my E-mail, I will check.
