FilePath after ellipsis for too long path

As of yesterday, PDF documents are no longer generated. In the event viewer I get this message

[Debug] 3944-24 (QueueWorker) pdfforge.PDFCreator.Core.Workflow.ComposeTargetFilePath.TargetFilePathComposerBase.ComposeTargetFilePath: FilePath after ellipsis for too long path: \cinegate.hq\FileShare$\MegRental\PDF\007_BERLIN\P\KVA_97135_01_007_BERLIN_P_20230627_0921_aga.pdf
[Error] 3944-24 (QueueWorker) pdfforge.PDFCreator.Core.Workflow.ConversionWorkflow.RunWorkflow: Final OutputFileTemplate is invalid rooted path \cinegate.hq\FileShare$\MegRental\PDF\007_BERLIN\P\KVA_97135_01_007_BERLIN_P_20230627_0921_aga.pdf
TargetDirectory_InvalidRootedPath

furthermore it always cuts off the first backslash, although everything is entered correctly in the tokens. here the tokens

[[[pfad:\\cinegate.hq\FileShare$\MegRental\PDF]]]
[[[kunde:007_BERLIN]]]
[[[drehtitel:P]]]

I have already applied all updates and restarted the server. I use the PDFCreator Server Version 3.1.0 on a Windows Server 2022.

What can I do?
