This update caused a problem.
Any ideas?

Well this isn't the solution.
But there is a segmentation fault happening with latest version of Synergy and Metamod.
With the PDB here is what i found.

Using metamod compiled from the master branch

This is caused by attempting to read any data that lies within the .voltbl section in Synergy's binaries. It looks like Windows blackholes sections that don't have any characteristics set.

I changed Metamod's source code to skip the backend checking but Sourcemod is the one that segfaults now.
It had to do something with reading the pointer to the loaded server.dll from Synergy

Edit:it could be what @IntriguingTiles is saying cause it segfaults when reading the server.dll from synergy's binaries

As a workaround, you can replace lib.memorySize = opt->SizeOfImage; with lib.memorySize = opt->SizeOfCode + opt->SizeOfInitializedData + opt->SizeOfUninitializedData;, which will work with Synergy's binaries for both metamod and sourcemod. However, this relies on code and data being the first few sections in the binary, which isn't guaranteed.

I checked the sections with dumpbin well this is what i found

Putting @IntriguingTiles workaround on both metamod and sourcemod worked for Synergy i haven't tried it on other games

[IntriguingTiles]

Synergy's development beta branch now has characteristics set for the .voltbl section for engine.dll and server.dll, so this will no longer be an issue once the update is released to the public branch.

A good to know but the problem right now is outdated vtable offsets from Synergy which makes sourcemod plugins unable to load
