Likely to be caused by #32741 (only PR merged into that IB, and seems to be related)

[christopheralanwest]

I suspect that the issue is that the global tag at

cmssw/DQM/Integration/python/config/FrontierCondition_GT_cfi.py

Line 3 in dd931b1

GlobalTag.globaltag = "111X_dataRun3_HLT_v3"

should be replaced with 112X_dataRun3_HLT_v1, which differs from the existing tag by the addition of the new record:
https://cms-conddb.cern.ch/cmsDbBrowser/diff/Prod/gts/111X_dataRun3_HLT_v3/112X_dataRun3_HLT_v1

[jfernan2]

I have created #32800 following @christopheralanwest 's comment

[silviodonato]

@jfernan2 @christopheralanwest could you clarify if #32800 #32803 are needed for the MWGR? My understanding was that the global tag is taken elsewhere during the MWGR, but probably I'm wrong.

[jfernan2]

At least #32800 is needed since DQM will be running in 112X
Despite GT can be changed manually at P5 DQM machines by DQM DOC, we usually make PRs for every big release change on this file to track and log which GTs are being used for MWGRs, see:

https://github.com/cms-sw/cmssw/commits/18442d459ff6789a404241f5dcd7633ad51a29e7/DQM/Integration/python/config/FrontierCondition_GT_cfi.py
Modification of Express GT is also needed as @mmusich pointed out in
#32800 (comment)
Thanks

[silviodonato]

Solved by #32800 #32803
